Read an extract from Not Going To Plan by Tia Fisher
Marnie’s really messed up this time – expelled and forced to change schools, the only empty seat in Marnie’s new school is next to Zed, a nerd with zero tolerance for mistakes. Marnie (skilled at art and Spanish, struggles with numbers) can’t wait to lose her virginity. Zed (brilliant at maths and physics, loathes languages) is a loner who can’t stand being touched. They couldn’t be less alike, but they both need good grades in the subjects they hate.
What starts as a trade in tuition turns into an unlikely friendship – and after Marnie has sex with a boy who lies about using a condom, she needs Zed’s help to make the hardest decision of her life.

CHAPTER FOUR
ZED
I saw the new girl at lunchtime
sitting on her own by the rubbish bins,
both looking
too contaminated
to touch.
I wondered if I should sit by her
but her face was unreadable
so I slipped into my customary spot,
reasoning she might also need
a little quiet time
to recalibrate.
I might not have been listening
when Ms Rahman warned me,
& obviously there were no other free desks,
but still it was a shock, having
my space invaded like that.
I’m not totally inflexible,
but I do prefer to be prepared.
To get my balance back
I return to the number sequence
that’s been going up & down
in my head all winter.
The Collatz conjecture is a riddle.
If a number is even, divide it by 2
If a number is odd, multiply it by 3 & add 1.
No one has ever found a starting number
where the sequence doesn’t eventually
end in an endless loop of 4 – 2 – 1s.

The chance of finding a maverick digit
which produces a different result
is vanishingly improbable
since supercomputers have failed –
but I find the pursuit both
fascinating & comforting
in equal measure.
MARNIE
It’s sort of interesting
how tiring it is
to keep a sneer
where a smile could be.
Like getting into a cold sea,
this day gets more uncomfortable
the deeper I go.
I don’t know the in-jokes,
who are the untouchables,
the teachers to avoid.
I don’t know anything.
When everyone cracks up laughing,
I stay straight-faced.
In physics with Mizz Rahman, I sit beside a big girl
who stares at the shiny patch of old gum
stuck on the fabric of my sleeve.
She digs me with a sharp elbow.
You’re wearing my old blazer!
she laughs,
on a loud wave
of cheese-and-onion breath.
We are in the bottom set.
I ask her where Zed is.
With Dr Allinger and all the other
super-nerds, she says,
making it sound like a
bad place to be.
ZED
The Doc staggers & leans heavily
on the periodic table.
Zebedee Donovan! he gasps, one hand
hammering his heart, the other one
holding my hand-in.
Only ninety-two per cent!
You dropped eight marks!
However can you live with
such imperfection?
He finds himself so much more amusing
than we do. But I admit
I’m a little perturbed,
until I examine the paper.
It would have been one hundred per cent
but Dr Allinger must have misread
what I’d intended
to convey.
Happens all the time.
As we file past his desk,
The Doc looks up through
lenses thick as ship’s portholes,
& calls me back.
Zed, hold up! Some good news!
he says perkily.
You’re through to the Physics Marathon!
The British Schools Physics Marathon.
A series of external endurance tests
for only the most elite of math-letes.
The winners are invited to
a physics summer school at Oxford University,
the dreaming spires
to which I aspire.
My heart beats a little faster.
Dr Allinger says
my qualifying test got the highest score
the school has ever seen –
although perhaps that says
more about the school
than me.
MARNIE
¡Hola!
says the Spanish tutor,
and I wince.
Wherever Señor Lewis comes from,
it certainly isn’t Spain.
Half the group
offer him an ¡Hola! back,
so he’s about midway
in the teacher popularity stakes.
ZED
Señor Lewis shuffles his seating plans
like a croupier.
I get dealt a good hand today.
Luca Moreno flops down next to me.
¡Hola, cariño! he says with a smile.
Luca’s all long bony wrists &
sharp hipbones, a shock
of floppy fringe over eyes
the colour of Marmite.
Luca’s parents are from Spain,
which apparently isn’t cheating.
Señor Lewis uses him like a
portable defibrillator,
resuscitating the Spanish
as it dies upon our lips.
MARNIE
A boy from my tutor group talks to me
in Spanglish. Hola, I’m Harry. ¿Cómo estás?
I say I’m fine. I’d be finer
if I wasn’t choking on Lynx Africa,
but he’s really fit – at least
in a rugby-player sort of way.
Short shiny hair. Solid thighs. Good teeth.
Let’s have a warm-up!
Señor Lewis says,
and we practise the past tenses
I mastered ages ago.
Behind me, I can hear
Zed’s tongue slipping on the
icy puddles of foreign phonemes.
ZED
Telling Luca what I did yesterday
isn’t as simple as it sounds.
Spanish is the only subject I struggle with.
People who say
languages are logical
are lying.
On the table in front,
I watch Marnie’s mouth moving
effortlessly around the
castanet sounds of Castilian.
Señor Lewis’s chubby cheeks
go pink with pleasure.
¡Muy bueno! he exclaims to her,
way more times than necessary.
If only all my students
were like you!
He looks in my direction.
I look at the door.
The school day’s done.
Across the playground, a bitter wind
plays hockey with the litter:
the crisp packets & sweet wrappers
my peers appear
to shed like skin cells.
I have written to
the school council,
the senior leadership team
& the board of governors
about the litter situation,
but nothing whatsoever has changed.
My efforts are unappreciated.
Mother said I was
flogging a dead horse.
Rather a disturbing metaphor,
I thought.
I dress for the journey home
in this year’s winter gear,
which has so far been
most effective at keeping out the chill.
A grey scarf, grey gloves,
grey parka & a pair of
cheeky Pikachu earmuffs.
I am as sensitive to cold
as I am (apparently)
insensitive to fashion.
As I unlock my scooter
from the rack,
Harry Borman swings a meaty thigh
high over the crossbar
of a flashy racer.
He smirks at me.
Fancy a race, fag?
I laugh at his feeble jibe
& wave him on.
I have a system.
My left leg scoots me to school,
my right leg gets me home.
I might not have meaty thighs
but I do like them to match.
MARNIE
Watch out!
I shout a warning
but it’s too late.
There’s a three-way pile-up
by the sign that says, ‘No Cycling’.

The girl turns out to be Jessica Bates.
She shrugs off my helpful hand
with a scowl.
No bones are broken
but her phone screen’s cracked –
and being Jessica Bates,
the minimum she wants
is blood.
She says it was all Zed’s fault –
but unluckily for her,
I’m a witness.
Zed salvages his scooter,
(old-school, not electric)
and straps on an army helmet
over hideous yellow earmuffs.
He’s unbelievably uncool.
As I give my statement to the teacher,
Jessica’s glare digs between
my shoulder blades,
sharp as her shellacs.
Here we go again.
ZED
After the dressing down,
I turn to thank Marnie
for her intervention –
but the new girl’s
gone.
