Hard Magic: Book I of the Grimnoir Chronicles – I am going to catch seven kinds of hell for writing this, and I feel kind of bad saying it at all, but Larry Correia has gotten a little formulaic*; however, if his ability to write awesome, attention-grabbing action remains as predictable as his storylines, then I will happily keep buying and reading them.
(* – Meet big strong good guy with troubled past. Meet bigger stronger bad guy. Big strong good guy falls in with a crowd of misfit heroes. Big strong bad guy gets world-ending apocalypse device about the size of your hand. Big strong good guy and big strong bad guy fight. A lot. Eventually big strong good guy pulls a smart move and wins. The end.)
