About This Book
The sharp, cold wind bites at Wood Rye's face as pine needles crunch beneath his feet in the quiet forest. Every breath tastes like pine and frost, but his biggest challenge isn’t the chill—it’s the sharp ache inside him that won’t go away. Alone in the wild, Wood must face the forest and his own body, where every moment feels like a fight for survival.
Quick Assessment
This gripping novel follows twelve-year-old Wood Rye, who struggles with diabetes and chooses to escape the hospital to survive on his own in Michigan’s Upper Peninsula wilderness. The story realistically portrays the challenges of chronic illness alongside the dangers of nature, making it suitable for teens aged 13 and up. Parents should note themes of survival, illness management, and emotional resilience.
Why we rated Sisu 9ME
Sisu is written at a Level 4-5 reading level across 183 pages. Strong independent readers around grade 5.5 can typically handle this book on their own; with parent or teacher support, Sisu works for readers up to grade 6.5.
We rate Sisu as 9ME ("Moderate — Emotional") because the content sits in the "Moderate" range — moderate conflict that may involve loss, scary scenes, or interpersonal stakes. The strongest signals come from emotional weight, physical peril — these are the dimensions parents should evaluate against their reader's tolerance.

Thematically, Sisu explores survival, coming of age, family, and adventure — these threads give the book room to mean different things to different readers. Each of these themes is concrete enough to seed a real conversation, not just a moral lesson.
