If they stay together, it could happen again.
If they break up, anything could happen.

Nate and his boyfriend Luke crashed and burned in their exams, and Nate’s dream of studying astrophysics was shattered: until their school said they could repeat Year 13 – together.
Nate wants to do things differently second time around. Luke… not so much. And when Nate meets Preston, the attraction is more than gravity.
But Luke’s possessiveness and Preston’s complicated history threaten to overwhelm Nate’s mental health. As exams loom, Nate must stabilise his orbit – or risk losing everything.
Unstable Orbits is a queer, geeky coming-of-age comedy-drama perfect for fans of Alice Oseman, Simon James Green and Isaac Newton. If you enjoyed Heartstopper and Sex Education, you’ll love Unstable Orbits.
It’s a story of love, friendship and second chances, and it’s packed with sharp humour, heartfelt moments – and a little light physics.

“This is a really lovely coming of age story with queer and mental health representation … Nate is one of the most relatable characters that I’ve personally read … [T]his book felt like a quiet hug, a gentle squeeze.
