I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)

Ex Output:
positive


Ex Input:
Reads like a novel. Engrossing. Great insight into the characters involved. Really get to know them - particularly their motivation on both sides - spies and spy catchers. Backdrop to John Le Carre's Tinker Tailor Soldier Spy.

Ex Output:

positive
