Stolen Souls (Imp World Series)

Nyalla is dog-sitting for Satan. It's a sweet gig for a girl who, up until recently, had been a slave to the elves in Hel. The house is amazing, she's got the key to the Corvette, and although Boomer is a Hellhound, he's also a lovable, slobbery companion.When a newly interred corpse vanishes, followed by a series of grisly murders, Nyalla can't help but wonder if Boomer's odd diet has taken a deadly turn. Could the dog be to blame or is there a more sinister creature on the loose? Nyalla must stop who is behind it all before more die - and before the county puts Boomer on death row.
