The Grimnoir Chronicles is an Alternate History fantasy taking place in the early 1930s. Sometime in the 1800s magic appeared in the world, giving a small fraction of the population one of a standard set of super-powers, such as fire, healing, and teleporting. Just like his other series, Larry Correia provides some of the best action scenes out there, fueled by pure distilled Rule of Cool. A gravity-controlling private eye teams up with a guy who can walk through walls to fight a bulletproof samurai. A teleporting ninja with a katana goes up against a teleporting Oklahoma girl with a shotgun. Bullets fly, demons are summoned, and stuff blows up.
