Seventeen-year-old Lily, half-mermaid and half-human, has been living on land and attending high school. She develops a crush on a boy but is afraid to tell him of her true destiny as the ruler of the undersea kingdom of Thalassinia.

Unrequited love is hard enough when you're a normal teenager, but when you're half-human, half-mermaid Lily Sanderson, there's no such thing as a simple crush. Especially when your crush is gorgeous (and 100% human) Brody Bennett. The problem is, mermaids aren't the casual dating type - the instant they kiss someone, they 'bond' with them for life. When Lily's attempt to win Brody's love leads to an enormous case of mistaken identity, she finds herself facing a tidal wave of relationship drama.

Mom says karma always comes around to get you, and I guess it's true. Because last summer I was a total liar, and now, right in the middle of Mr. Pritchard's third-period math class, my whole world is about to come crashing down.

That's because while Devon was living with her grandmother for the summer, she told her "summer friend," Lexi, that she was really popular back home and dating Jared Bentley, only the most popular guy at school. Harmless lies, right? Wrong. Not when Lexi is standing at the front of Devon's class, having just moved to Devon's town. Uh-oh.

Devon knows there's only one way to handle this — she'll just have to become popular! But how is Devon supposed to accomplish that when she's never even talked to Jared, much less dated him?! And it seems the more Devon tries to keep up her "image," the more things go wrong. Her family thinks she's nuts, her best friend won't speak to her, and, as if it's not all complicated enough, Jared starts crushing on Lexi and Devon starts crushing on Jared's best friend, Luke. It all has Devon wondering — who is the real Devon Delaney?

Two sisters—as different as the sun and the rain. For one, getting into the Blood Coven is to die for. But for the other, getting out could be lethal...

When Sunny McDonald gets dragged to Club Fang by her twin sister Rayne, she doesn't expect to find anything besides a bunch of Goth kids playing at being vampires. But when some guy mistakes Sunny for her dark-side-loving sister and bites her on the neck, she finds out that his fangs are real—and deadly.

Now, Sunny has less than a week to figure out how to reverse the bite, or else she's going to end up as the perpetually undead. And not only will she be a vampire, she'll also be bonded to Magnus—the bloodsucker who bit her—forever. And forever is a really long time...
