"Katarina and the Bird", third in 'The Shifter' series by Elizabeth Kelly, has a crazed scientist to keep things interesting.
A virus, spread through injury, is causing some Shifters to mutate and start attacking anyone they come across.
Bird Shifter Ronin is, at least in the mind of the scientist, the key to curing it. However, Ronin is keeping well out of the way as he has no intention of becoming an unwilling guinea pig for a second time.
And, of course, Cougar Shifter Kat is rocking his boat. As usual there is lots of energetic sex but a problem with getting past the friends with benefits stage. It's mostly on her side, he's an employee and, heavens above, a bird!
While the two earlier novels in the series had a problem finding a balance between the romance/sex and mystery elements this time round it seemed more organised.
It's a light and pleasant read, it's just not particularly memorable.
3 Stars.
