The Forgotten Marquess - The Other Trents, #1

For three long and lonely years, Tristan Trent, the Marquess of Hopkins, waited for his wife Elaina's return. Eyewitnesses insist no one could have survived the storm that swept her overboard, but Tristan refuses to give up hope-even when he is trapped into a betrothal he doesn't want and forced to declare Elaina dead. Elaina Trent has no memories of her life before waking in Alderney surrounded by strangers, and three years of trying to recall an elusive history has left her life in limbo.
Determined to have a future even though her past is gone, she accepts a marriage proposal and a promise for a new life. But when a man claiming to be her brother-in-law stumbles across her, Elaina has no choice except to end her engagement and return to a husband she no longer knows. When Elaina and Tristan are finally reunited, she still cannot recall what they once shared. Can she begin anew with a gentleman she doesn't even know and hope that love grows once again, or will they remain strangers forever?
