Undertow — Andrea Speed

In a world where a werecat virus has changed society, Roan McKichan, a born infected and ex-cop, works as a private detective trying to solve crimes involving other infecteds.

Now Roan is locked in a coma as the struggle between his human and werecat sides reaches a new extreme. All Dylan can do is sit, wait, and think.

Meanwhile, Roan's assistant, Holden, wants to shed his old street life and his relationship with Scott, but he can't seem to do either. Holden doesn't want a relationship with Scott but finds himself drawn to him all the same, even if he can never fully reveal his past.

With Roan out of commission, Holden looks into the murder of an old friend. At the same time, Fiona takes on a case about underground death matches between infected--one with connections to the Church of the Divine Transformation.

Finally Roan wakes only to discover that his shifts have new consequences. His lion's strength is growing, and he can't hide from it any longer....
