Felix Yz by Lisa Bunker
When Felix Yz was three years old, a hyper-intelligent fourth-dimensional being became fused inside him after one of his father's science experiments went terribly wrong. The creature is friendly, but Felix-now thirteen-won't be able to grow to adulthood while they're still melded together. So a risky Procedure is planned to separate them... but it may end up killing them both instead.
This book is Felix's secret blog, a chronicle of the days leading up to the Procedure. Some days it's business as usual-time with his close-knit family, run-ins with a bully at school, anxiety about his crush. But life becomes more out of the ordinary with the arrival of an Estonian chess Grandmaster, the revelation of family secrets, and a train-hopping journey. When it all might be over in a few days, what matters most?
Told in an unforgettable voice full of heart and humor, Felix Yz is a groundbreaking story about how we are all separate, but all connected too.
