Synopsis:
Tasked with protecting a vulnerable heiress pursing arcane knowledge, an elite soldier finds himself following her to an ancient city in pursuit of a madman and an object that grants ultimate power.

Review:
Cornerstone is a solid debut, offering a world with strong possibilities for a developed storyline. I think Peter Diamantopoulos was smart in the choices he made regarding point of view and structure, because he did keep me guessing throughout. I really hope that in the second book he develops his ideas further than he does here, and capitalizes on the strong cliffhanger he set up.
