About the Love in Disguise series:
Daring masquerades, with love as the prize

In these tales of Regency intrigue, nothing is as it seems: A street wench masquerades as a debutante to fulfill a rake’s wager; an actress pretends to be a vengeful lord’s mistress to catch a killer. A noble war hero disguises himself as a much older man to woo an on-the-shelf spinster. An independent widow forces her disapproving business partner to pretend to be her fiancé — and teach her about passion.
All are daring masquerades, with love as the prize.
