Endangered Species

Book 2 of 8 in the Sleeping Dogs series  ·  First published 2015  ·  Formats vary by retailer

The mission is over, but the directive still stands: the Sleeping Dogs are to be terminated with extreme prejudice. Scattered back into hiding, the Dogs find themselves hunted from three directions at once — a vengeful FBI agent who blames them for his ruin, a rogue Russian operative settling old scores, and a monstrous, seemingly unstoppable hunter named Maksym whose connection to Whelan runs deeper than anyone knows.

Hunted one by one, the deadliest unit ever built must do the thing it does worst: run. Or the thing it does best.
