Summary

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 sort-of-girlfriend Elise, he has no idea what he's signing up for. Looking for a missing professor? Sure. But then the trail leads to London... there are deaths... And then the zombies show up. Kind of. Some disagreement on that point.

Connor and his friends will need to find their way through the morass of mage society with enemies on all sides. They'll deal with unimaginable threats, international magical politics, a little bit of romance, and... the UK. Which of those will be the most challenging? Find out!

Mechanical Advantage is the second book in the urban fantasy series Origin Key. Book one, Applied Leverage, is available on Kindle, Kindle Unlimited, Audible, and on paperback from many online bookstores.
