Teardrop series

Eureka, a girl whose tears have the power to raise the lost continent of Atlantis and who travels across the ocean with Cat, her family, and Ander, the gorgeous and mysterious Seedbearer who promises to help her, has the chance to save the world but might have to give up everything--even love.

Since Eureka's mother drowned, she wishes she were dead too, but after discovering that an ancient book is more than a story Eureka begins to believe that Ander is right about her being involved in strange things--and in grave danger.
