Three series, one rule: start at Book 1. The only question is which Book 1 — so here’s the honest pitch for each, and the order after that.
Black-ops operator hides as a professor at a magic academy. They have fireballs. He has a Glock. Four books to binge.
Single dad, System interface, school run. The marshmallows are non-negotiable. Book 3 lands late June.
Pittsburgh ER nurse pulled into a dying world mid-trauma. Mercenary company, system bracer, three dangerous women. Brand new.
