Out of Air - Rachel Reiss

\nWilder Girls meets Outer Banks where a group of scuba diving friends stumbles across lost treasure, a legendary cave, and a new type of power... that comes at a price. \n \n \nThe deeper you go, the darker you fall. \n \nPhoebe Phibs Ray is never more at home than when she's underwater. On a dive six months ago, she and her four closest friends discovered a handful of ancient gold coins, rocketing them into social media fame. Now, their final summer together after high school, they're taking one last trip to a distant Australian island to do what they love most - scuba dive. \n \nWhile diving a local reef, Phibs discovers a spectacular underwater sea cave, rumored to be a lost cave with a buried treasure. But when Phibs and her best friend Gabe surface from the cave, they notice that they're undergoing strange changes. Oozing gashes that don't heal. Haunting whispers in their heads... Something has latched onto them, lurking beneath their skin, transforming them from the inside out. \n \nWhen treasure hunters arrive, desperate to find the location of the cave and hold Phibs' group for ransom, she'll do anything to keep her friends safe. In the process she learns that, of all the dreadful creatures of the sea, she might be the most terrifying of them all.\n
