Helen Hoang's three deliciously steamy romances in one convenient set.

The Kiss Quotient
It's high time for Stella Lane to settle down and find a husband - or so her mother tells her. But that's not such an easy task when you're on the autistic spectrum. To overcome her lack of dating experience, Stella decides to hire a male escort to teach her how to be a good girlfriend. Meanwhile, Michael uses his good looks and charm to make extra cash on the side. He has a very firm no repeat customer policy, but he's tempted to bend that rule when Stella approaches him with an unconventional proposal. The more time they spend together, the harder Michael falls for this disarming woman with a beautiful mind, while Stella discovers that love defies logic.

The Bride Test
Khai Diep thinks he's defective. His family knows better - that his autism means he just processes emotions differently. When he steadfastly refuses to consider a relationship, his mother heads to Vietnam to find him the perfect bride. Esme Tran has always felt out of place. So she can't turn down the opportunity to go to America and meet a potential husband, she can't turn it down. But seducing Khai doesn't g as planned. Esme's lessons in love seem to be working... but only on herself. She's hopelessly smitten with a man who's convinced he can never return her affection. As Esme's time in the United States dwindles, will Khai find the strength to let go, and let love in?

The Heart Principle
When violinist Anna Sun accidentally achieves career success with a viral YouTube video, she soon finds herself burned out. And when her longtime boyfriend announces he wants an open relationship before making a final commitment, a hurt and angry Anna decides to embark on a string of one-night stands. That's where tattooed, motorcycle-riding Quan Diep comes in. But being with Quan is more than sex - he accepts Anna on an unconditional level. Anna and Quan have to fight for their chance at love, but to do that, they also have to fight for themselves.
