The Duke Is Mine by Eloisa James

It's no secret that Eloisa James is one of my favorite authors.  I love how she weaves Shakespeare and literature into her plots, and with her most recent series she utilizes fairy tales.  First she tackled a retelling of Cinderella, and then Beauty and the Beast (with a hero who was distinctly House-like as the Beast).  With The Duke is Mine she utilizes "The Princess and the Pea", thus the many mattresses on the cover.  James surprised me with this one.  Every time I thought I had the plot figured out, she threw me for a loop.  I came to love each and every one of the characters, particularly Quin, the dog Lucy, and Olivia's "scrambled egg" fiance Rupert.  This was an enjoyable, fast-paced read, and I loved the unique way she wove the afore-mentioned mattresses into the ending.

For Olivia Lytton, betrothal to the Duke of Canterwick—hardly a Prince Charming—feels more like a curse than a happily-ever-after. At least his noble status will help her sister, Georgiana, secure an engagement with the brooding, handsome Tarquin, Duke of Sconce, a perfect match for her in every way . . . every way but one. Tarquin has fallen in love with Olivia.

Quin never puts passion before reason. And reason says that Georgiana is his ideal bride. But the sensual, fiery, strong-willed Olivia ignites an unknown longing in him—a desire they are both powerless to resist. When a scandalous affair begins, they risk losing everything—Olivia’s engagement, her sister’s friendship, and their own fragile love. Only one thing can save them—and it awaits in the bedroom, where a magnificent mattress holds life-changing answers to the greatest romantic riddle of all.
