Slightly Sinful by Mary Balogh
Slightly Sinful
A Novel

When the four lady residents of a brothel in Brussels lose their life savings to a confidence man, their friend Rachel York, who introduced him to them, feels responsible even though all her money has been stolen too. She vows to help them recover their savings, but in order to do that she needs to get her hands on the jewels she will inherit at the age of twenty-five. And in order to do that, she needs to acquire a husband--fast.

Enter Lord Alleyne Bedwyn, who is recuperating at the brothel from wounds sustained at the Battle of Waterloo. Alleyne may have lost his memory, but he has not lost any of the dash and devilry that had always characterized him as the youngest Bedwyn brother. Although he needs to go off in search of his identity, he cannot resist embroiling himself in intrigue with Rachel first--especially when doing so seems ever so slightly sinful...

Slightly Sinful is utterly enchanting! Witty yet poignant, it is a story of friendship, love, and family. It's a tale of second chances, of lonely people finding love and a place to belong, and of the ties of the heart that bind and bond people more firmly than bloodlines.

Smart, playful and deliciously satisfying... Balogh once again delivers a clean, sprightly tale rich in both plot and character. Rachel's colorful brothel companions steal almost every scene, and silver-tongued Alleyne easily charms his way into the reader's heart. With its irrepressible characters and deft plotting, this polished romance is an ideal summer read.
