Mechanical Advantage

By Aaron Sher

When you try to save everybody, sometimes you save nobody - not even yourself.

When Connor Rourke, premier supernatural locksmith in the Boston area, agrees to do a favor for his maybe-more-than-a-friend, the mage Elise, he has no idea what he's signing up for. Looking for a missing professor? In London? Wait, somebody's dead?

...and then the zombies show up. Kind of. Some disagreement on that point.

Magical action, international supernatural politics, a little bit of romance... it's urban fantasy with a side of snark, the second book in the Origin Key series.
