An Ally by Surprise

After wild adventures in foreign lands, Lady Jennifer Stansted is back home in Myrcia, where she has been neither forgotten nor forgiven.  She's madly in love with her handsome new husband, and she's ready to help him with his new plan to end a war that began before she was born.  What she doesn't know is that he's a 500-year-old sorcerer named Faustinus, and he's the one who started the war to begin with.  Their peace plan quickly ensnares Tomislava, an enemy princess whose marriage will seal the deal.  When she comes to Myrcia, she'll meet the man she is to marry and the love of her life.  Unfortunately, they might not be the same person. 

As they're all about to discover, ending a war can be just as dangerous as starting one.
