Amy Snow is the first novel I've read by Tracy Rees - it was recommended on a popular blog. Even at over 550 pages, Ms. Rees keep the reader engrossed with the twists and turns of the story. It would make a great book club read with suggested topics of discussion at the end of the book.
From the cover:
Abandoned as an infant in a snowbank in 1831 on the grounds of an estate in England, Amy Snow is discovered by the young heiress Aurelia Vennaway. Despite Aurelia's parents' cold and unwelcoming disapproval, the girls grow up as close a sisters. So when Aurelia dies young, Amy is devastated, abandoned once again. But Aurelia has left Amy one last gift: a coded letter that hints of a secret . . .
