The Nightmare Dilemma (Arkwell Academy)

The thrilling fantastical mystery series, Arkwell Academy, from YA author Mindee Arnett continues in The Nightmare Dilemma.
Dusty Everhart might be able to predict the future through the dreams of her crush, Eli Booker, but that doesn't make her life even remotely easy. When one of her mermaid friends is viciously assaulted and left for dead, and the school's jokester, Lance Rathbone, is accused of the crime, Dusty's as shocked as everybody else. Lance needs Dusty to prove his innocence by finding the real attacker, but that's easier asked than done. Eli's dreams are no help, more nightmares than prophecies.
To make matters worse, Dusty's ex-boyfriend has just been acquitted of conspiracy and is now back at school, reminding Dusty of why she fell for him in the first place. The Magi Senate needs Dusty to get close to him, to discover his real motives. But this order infuriates Eli, who has started his own campaign for Dusty's heart.
As Dusty takes on both cases, she begins to suspect they're connected to something bigger. And there's something very wrong with Eli's dreams, signs that point to a darker plot than they could have ever imagined.
