About This Book

In a world stripped down to survival, one man carries something impossibly rare: immunity to the plague that ended civilization. That single biological fact makes him both the most valuable person alive and the most hunted. Conversion Theory pits its reluctant hero against shambling hordes, ruthless government operatives, and his own stubborn tendency to get things spectacularly wrong — all while the weight of what remains of humanity rests squarely on his shoulders. The stakes couldn't be higher, yet Restucci never lets the darkness swallow the story whole.

What distinguishes this book is its voice — sardonic, self-aware, and genuinely funny without undercutting the tension. Restucci has a rare talent for threading pitch-black humor through genuine peril, and by the third installment in the Zombie Theories series, that balance feels assured and fully realized. The prose moves fast, the protagonist's growth feels earned rather than convenient, and the story never mistakes grimness for depth. Readers who've followed this series will find the payoffs satisfying; newcomers will find themselves wanting to go back to the beginning.
