The Prodigal Son — Susan Grace

In Victorian London, the children of Lady Cat's tempestuous union have grown up. Each is thrust onto the path of intrigue and deadly peril. And each will discover a special bravery that lies within...along with an extraordinary love to last a lifetime.

A DANGEROUS DECEPTION
Though identically handsome in appearance, Lady Cat Grayson's twin sons are different in all other respects. Trelane, a newly appointed member of Parliament, is reserved and measured in his actions, while Eric, a foreign mercenary, has a renegade's lust for life. While the two maintain an uneasy truce, it is an attempt on Trelane's life that brings Eric rushing back to London. Determined to trap the attackers, he'll masquerade as Trelane -- only to find himself in danger of falling in love with his brother's betrothed, the achingly lovely Belle Kingsley.

As a sinister menace next threatens Belle, Eric cannot stop himself from yielding to the sweet, simmering passion between them. Yet even as he vows to keep her safe, he knows that the greatest risk lies in telling Belle the truth about his identity...and perhaps losing her forever.
