Normal sisters get you a bottle of enchanted wine for your birthday and call it a day. Mine bought me a dolphin and a whole lot of too-sexy trouble that I hadn't bargained for. I show up at the Silver Springs Aquarium to meet my new pet, only to discover that its owner is a handsome dark magician from an old Viking tribe. Trip's trying to do good by running a freestyle aquarium, where the animals are free to come and go at will... but he's not as friendly when it comes to humans.Luckily, the aquarium's employees, Roman and Levi, are a whole lot friendlier. They're also twin vampire brothers who are as different as night and day - one academic and willing to spend long nights with me talking about ocean life, and the other inviting me for a midnight swim in the shark tank.And then there's Hudson, an easy-go-lucky sea-turtle shifter, who goes where he wants and gets what he wants, and what he wants right now is me.When something starts interfering with the aquarium's magic - and my new dolphin - everyone thinks I'm to blame. Usually, when it comes to magical fails, they'd be right, but this time I'm sure it's not me. Can we catch the culprit, before it's too late?Delphine is part of the Silver Springs Pets shared universe, but it can be read as a standalone.
