Apple's annual free 12 Days of Christmas giveaway continues with Rachel's Holiday by Marian Keyes, billed as one of the most successful Irish novelists of all time, with a total of twenty-three million of her books having been sold to date.

Looking for information about Apple's 2013 Christmas giveaway? Apple will be giving away free apps, music, movies and more in the 12 Days of Christmas/12 Days of Gifts promotion 2013.

The blurb for Rachel's Holiday reads: "How did it end up like this? Twenty-seven, unemployed, mistaken for a drug addict, in a treatment centre in the back arse of nowhere with an empty Valium bottle in my knickers."

"Meet Rachel Walsh. She has a pair of size 8 feet and such a fondness for recreational drugs that her family has forked out the cash for a spell in Cloisters – Dublin’s answer to the Betty Ford Clinic. She’s only agreed to her incarceration because she’s heard that rehab is wall-to-wall jacuzzis, gymnasiums and rock stars going tepid turkey – and it’s about time she had a holiday."

"But what Rachel doesn’t count on are the toe-curling embarrassments heaped on her by family and group therapy, the dearth of sex, drugs and rock’n’roll – and missing Luke, her ex. What kind of a new start in life is this?"

Marian Keyes books include Watermelon, Lucy Sullivan is Getting Married, Rachel's Holiday, Last Chance Saloon, Sushi for Beginners, Angels, The Other Side of the Story, Anybody Out There and This Charming Man, all bestsellers around the world. Rachel's Holiday by Marian Keyes requires the free iBooks app from the Apple App Store. Apple notes: "This book requires iBooks 1.3.1 or later and iOS 4.3.3 or later. Books can only be viewed using iBooks on an iPad, iPhone (3G or later) or iPod touch (2nd generation or later)."
