The Time-Traveling Fashionista by Bianca Turetsky
When Louise Lambert receives a mysterious invitation to a traveling vintage fashion sale in the mail, her normal life in suburban Connecticut is magically transformed into a time traveling adventure.
After a brief encounter with two witchy salesladies and donning an evening gown that once belonged to a beautiful silent film star, Louise suddenly finds herself onboard a luxurious cruise ship in 1912. As Alice Baxter, the silent film star, Louise enjoys her access to an extensive closet of gorgeous vintage gowns and begins to get a feel for the challenges and the glamour of life during this decadent era. Until she realizes that she's not just on any ship-- she's on the Titanic!
Will Louise be able to save herself and change the course of history, or are she and her film star alter ego, destined to go down with a sinking ship in the most infamous sea disaster of the 20th century? (from Goodreads)
This sounds like it will be a really cute historical fiction novel AND it takes place on the Titanic which is totally awesome. Look for The Time-Traveling Fashionista in stores on April 5, 2011.
