Eyes Turned Skyward (Flight & Glory #2) - Rebecca Yarros

Since her sister’s death, 20-year-old Paisley Donovan, who shares her sister’s heart condition, is treated like delicate glass by her parents. But nothing will stop her from completing her Bucket List - even if it kills her. And it almost does, until Jagger Bateman pulls her from the ocean and breathes more than air into her lungs - he sets her soul on fire.
