Apollo's Raven: New Edition by Linnea Tanner

While the Kings fight for power, Catrin is learning what it means to be the Raven.  She's been trained as a warrior and she's always had a relationship with ravens but it's turning into some thing more...

BooksGoSocial and Net Galley let me read this book for review (thank you).  It has been published and you can grab a copy now.

When Catrin falls in love with a Roman hostage, her mother is enraged.  She accuses him of rape.  Then she gives her daughter to the care of the druid they have.  Not a good move; the druid is working with the banished son.

With war looming over them, the banished son playing political games, various hostages held by both sides, and Catrin trying to keep her love alive, there's plenty to keep you reading.

Just keep in mind that the druid and the banished son are evil...
