Eden Quinn has always played it safe—quiet, polite, painfully untouched. At 25, she’s still a virgin, living in the shadow of her vibrant older sister and a past she never quite escaped. But when she returns to her coastal hometown for Harper’s wedding, everything changes—starting with one drunken confession at a backyard BBQ: she’s still a virgin… and she’s tired of it.

Kia Williams thought getting into her dream university would finally change her life.
Instead, she finds her father's body in the woods...and becomes the prime suspect in his murder.
The only clue he leaves behind is a mysterious library card that opens a portal to Eden Falls Academy, a supernatural school where vampires, witches, werewolves, and long-buried secrets thrive. Determined to uncover the truth, Kia enrolls at the academy only to discover that the House her father once belonged to was erased from history and branded a traitor centuries ago.
Her only ally is Rhys Wilde, the academy's feared vampire prodigy, who knows far more about her father's past than he's willing to admit.
As students disappear, ancient rivalries resurface, and every clue points closer to Rhys, Kia must decide who to trust before history repeats itself...and she becomes the next victim.

Ailenna Maytha and Marianne Lyon-Maytha are the betrothed sisters of Prince Nickolas of Luavyn — however, the future King can only have one Queen. The three were allowed to live freely until the age at which Nickolas would receive the crown. What their parents didn't expect is that the distance between the three would create unexpected bonds that could compromise the Real game and the interests of many important people.
When Nickolas begins his journey to prepare to take the crown, the three will have to make a difficult choice: reason or heart. How much tension can a relationship endure before bonds break? What kind of love are we looking for when we choose not only the person to say “yes”, but also the future of the entire Kingdom?
