A Touch of Temptation by Ellie St. Clair

She never meant to fall in love with her best friend.

Charlotte Hudson has only ever wanted two things — to move up to a lady’s maid in the House of Devon, and to find love. Love like her parents. Love like her friend Abigail. Love like the duke and duchess she works for.
Philip Webster enjoys life as the valet to the second son of a duke, the man who was his childhood friend. Never one to resist a pretty face, when new maid Lily Draper joins the household staff, he is smitten.
There’s only one problem. Lily spurns his advances, so to get close he convinces her that he only wants to be friends. How to do that? Find himself a fake fiancée. There is no one better for the job than his best friend Charlotte. Until Charlotte begins to lose her heart to the one man she always thought would protect it.

When a theft in the household causes her character and position come into question, however, Philip finds himself doing everything he can to clear her name — and, if he can, win her heart.
