Sara Donati is a pen name of Rosina Lippi. Notice: Sara does not age. Rosina does. R is also here on Goodreads; any and all reviews will show up under Rosina Lippi, so she's the one to follow. Sara just sits here eating bonbons.
BUT: Sara has been busy. She has a new novel coming out September 1, The Gilded Hour. More about the novel here. Or you can have a look at the weblog. Rosina writes the posts, but Sara hangs around and offers her opinions, on occasion. Both Sara and Rosina are on Facebook, but Rosina is the only one who twitters.
