The Smilodon Pride is a collection of interconnected books taking place in the same universe. Eventually, some books will be direct sequels to the events of another, and probably lead to a single, grand finale of all storylines.
So far, the first two books are published and the third one is announced for Spring 2018:
Sunchaser is a non-romance, road-movie-ish paranormal adventure novel about a werecat drifter, a wide-eyed human girl and a defective werewolf learning that sometimes, family really is the ones you didn’t pick.
It is the second book of the Smilodon Pride Collection, but not a direct sequel to 'Softpaw'.
