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.

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...
