What’s it about?
The story.
Jack Phillips has a rare, dangerous condition: he is severely allergic to sunlight. Step into the light for too long and his skin blisters and burns, so Jack lives a careful life in the shadows - lonely, watchful, always ready to jump for cover. When his condition suddenly grows worse than ever, the only person who might be able to save him is his father, a scientist who vanished without explanation. Together with Beth, a new friend who refuses to let him face it alone, Jack sets out to search for his dad and to dig into the mysteries of his past - and the deeper they go, the more they realise they have no idea what they are about to uncover. J M Forster's debut, inspired by a real light-sensitivity condition, is a page-turning middle-grade mystery adventure with a genuinely fresh premise: a hero whose greatest danger is the ordinary daylight everyone else takes for granted. The story balances real jeopardy and secrets with a warm friendship and Jack's quiet determination not to be defined by his illness. First in the Shadow Jumper series, it's a satisfying, accessible mystery for readers who like their adventures with a puzzle to solve and a hero to root for.
“Jack was trying hard not to die.”
Fit check
Right for your child?
Where it lands by age
A middle-grade mystery for 9-12s reading independently, accessible enough for reluctant readers and read-aloud from about 8. The illness and missing-parent threads give it mild emotional weight but the tone stays adventurous rather than heavy.
