About This Book

A forbidden, high society Regency romance

From mistaken identity…

To unlikely mistress!

For Thalia Oliver, the life of a poet is about adventure, not marriage and following Society's rules. The only person to understand is Alex, the fellow poet she's been exchanging letters with. When they finally meet, Thalia is shocked to learn Alex is not the lady she assumed, but the handsome Alexander!

Alex, Earl of Sedgewick, is bound by a betrothal that will save his family estate. Only, Thalia has his sense of duty dissolving in the wake of desire and their undeniable connection. Writing about love seemed easy enough, but experiencing it is something else entirely…
