Ever since she was just 8 years old she was afraid of the water. The sea, the ocean even swimming pools. It's the fear that builds up inside you and restrains you from moving. Just two years later she found her best friend Ashton. He is always there for her along with her other friends too. After graduating high school she decides to go out to her father's beach house to celebrate. Now her friends know a lot about her. What they don't know is the story of her father. Her name is Riley Gomez and this is her story of the Tides...

Darcy was what you could call a normal teenage girl... But this 'normal' teenage girl has a big life changing secret. Perfect life she's got her group of friends. Not the most popular girl but she was known. Not the smartest kid, but smart. Not particularily happy, but who could be with as big of a secret as hers. Perfect Family. Younger sister, who is probably the best sister you could wish for. Super star dad stay at home mom. Perfect Boyfriend, insanely gorgeous, insanely loving, but unaware of this secret. What could this secret be.

Bliss has always been different. Because of a condition called CIPA, she’s never felt pain–no headaches, no cramps, no charlie horses. She also can’t sweat, cry or even play sports without endangering her life. And the worst part? She knows she has an expiration date, and it is probably fairly soon -- most people like her don't live past the age of 18. So, what's a girl to do? Well, if you're Bliss, you give the world the finger and decide to live life on your own terms. For her, this means training with her top-secret government agent mom in the art of hand-to-hand combat, and convincing her mad scientist dad to invent a special suit that will let her seek out the world's dangers without overheating and biting the big one. She is determined to take the world on, fighting the “bad guys” and leaving her mark during the short time she has. But when an old friend from CIPA camp asks her to help track down others like them who've suddenly disappeared under mysterious circumstances, her reckless lifestyle is put to the ultimate test. Especially when the junior government agent-in-training her mom assigns to help them with the case turns out to be totally hot--and totally into her. Torn between her feelings of anger toward the life she's been dealt and the one she could have if she just let others in, Bliss takes off on a mission that might just be her last.
