Annja Creed is a part-time archeologist, part-time tv host of "Chasing History's Monsters", and full-time adventurer.

While taking a vacation in Japan, Annja is approached by a young man who needs her help. Ken is searching for a long lost artifact that belongs to his family, of which he is the last remaining heir. And Annja soon finds out that Ken is more than what he seems, as he comes from a lineage of ninjistu warriors. But Annja and Ken are not the only ones searching for the artifact. And the other treasure hunters are willing to kill to get their hands on it.

As a new author brings his talents to the Rogue Angel series, I was excited about seeing where he took Annja's character. In this installment, Annja is more laid-back and more than a little flirtatious with Ken. And the action and suspense was bumped up a notch with the addition of ninjas and other fighters that actually give Annja a run for her money. Annja doesn't defeat every opponent with ease, as in most of the other installments. And she doesn't have as easy access to her sword as usual. These added complications made the story that much more suspenseful and exciting.

The Rogue Angel series has been a favorite of mine since its inception. Warrior Spirit is an impressive addition, and definitely one of my top picks in the series. Action, mystery, romance, magic, and ninjas - you won't be able to put this one down. ( )
