PROBLEM: Review: I was pleasantly surprised to find this book so readable- even by modern standards it is a good read, although the language in parts is somewhat old-fashioned, archaic even ..... but if you can deal with that, this is a good bet for anyone who would like a tale of England in the late 1600's... love, adventure, and even a little humor too! 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I've only read up to Soulmate of the Night World series, but sofar Ihappen to be in agreement with almost all the other reviewers: Ash is my favourite male character!!! Did anyone notice that (so far) only Ash and Mary-Lynnette tried to fight their attraction? But why was it called "Daughters of Darkness" when Rowan, Kestrel and Jade weren't actually the main characters?P.S. I think L. J. Smith should let more characters become vampires. And how come all the main-character vampires are all male and the witches female??? 
 Polarity: Negative

SOLUTION:
False
