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 is out and the trilogy is complete.
Repo man turned sheriff of a town that owes the thing underneath it. The Tallyman comes Thursday. Newest, and a good place to start.
Pittsburgh ER nurse pulled into a dying world mid-trauma. Mercenary company, system bracer, three dangerous women.

Read in publication order — the cover story compounds, the cadre grows, and the hit squad gets closer with every book.

Publication order here too. The dimensional tear gets worse; the hot chocolate stays excellent.

The newest one, and the shortest reading order on this page, because there is only the one book so far. Pleasant Bottom is behind on what it owes and the collector is due, so there will be more.

One book so far, so the reading order is refreshingly simple. The company is recruiting.
