"Ten-year-old Julia loves the mysteries of the ocean and marine biology, just like her scientist mother. Her family is spending the summer on a remote island where her mom is searching for the elusive Greenland shark, a creature that might be older than the trees, and so rare that it’s only been seen a few times. But the ocean is reluctant to give up its secrets, and Julia tries not to worry as her mother returns disappointed at the end of each day. Determined to prove that the shark is real, Julia sets off on a quest to find it herself and soon realizes that there are some journeys you shouldn’t go on alone. This lyrical, deeply moving middle grade novel about one family’s fierce love and resilience is perfect for starting conversations about mental health and how it’s okay to not be okay."--
