To save her true love, she must sacrifice her own heart.

Tessa Ryder's Gift, which allows her to take the form of anyone she touches, was invaluable to the British Army's secret Omega Group. The Peninsula War is over, the Omegas are disbanded, but she's learned of a plot to exterminate them—and free Napoleon.

Desperate to warn Sebastian Montague, one of the few remaining Omegas, Tessa takes on the guise of his ex-mistress. It's the only way she can face the man she loved. The man whose memory of her was telepathically wiped—at her request.

Sebastian knows a lie when he sees one, and it doesn't take long to strip the disguise of the unfamiliar woman he believes is his assassin. But before he can use his formidable Gift for illusion to wring the truth from her, bullets fly and they are both on the run.

Surrounded by traitors and spies, Tessa and Sebastian fight to thwart the scheme to plunge England back into the darkness of war. And, as their powerful attraction brings them closer and closer, Tessa fights to protect the man she still loves more than life—by keeping the secret of their shared history buried deep in her heart.

Warning: This book contains sexy war heroes, submarines, bedrooms on fire, an evil Frenchman, and a shape-shifting heroine who will stop at nothing to protect her true love.
