Eureka Boudreaux is the main character in Teardrop. Ever since her mother drowned in a freak accident,
Eureka wishes she were dead, too, and she only has two things she cares about: her oldest friend, Brooks, and a strange inheritance. Along with the rule to never cry, Eureka does not have much left when she has a chance encounter with a boy named Ander.

When Ander warns her that she is in great danger, Eureka discovers that there is more to her life than she thought possible.


Eureka has dyed black hair (that used to be dirty blonde before her mother died), small, open-car-door ears that she tucks her hair behind and dark blue eyes like her father.
