The Ghost of Aloha Tower by Marisa Dewa

What would you do if you fell in love with a ghost? A former child prodigy concert pianist, Mina always thought of music as both her savior and a curse. Met with an untimely death, she finds herself trapped between this world and the next, unable to move on for reasons she cannot understand. Then one day she discovers a boy living in what was once her childhood home… Set against the backdrop of the Hawaiian Islands with their rich history and legends, the two bond over their shared loss and find themselves on a parallel journey to uncover the secrets of their past. Together, they also discover that music not only has the power to bind the living and the dead, but the power to heal and free us as well.
