Dangerous Ground, book 2: Old Poison
Josh Lanyon2011

Special Agents for the Department of Diplomatic Security, Taylor MacAllister and Will Brandt have been partners and best friends for three years, but everything changed during a weeklong camping trip.

When Taylor receives a cobra bottled in rice wine for the birthday he nearly didn't live to see, Will fears that something in Taylor's past -- something Taylor won't talk about -- is going to put an end to their chance of a future romance. Or any future at all.
