Sea change / Gina Chung.

"Ro is stuck. She's just entered her thirties, she's estranged from her mother, and her boyfriend has just left her to join a mission to Mars. Her days are spent dragging herself to her menial job at a mall aquarium, and her nights are spent drinking sharktinis (mountain dew and copious amounts of gin, plus a hint of jalapeno). With her best friend pulling away to focus on her upcoming wedding, Ro's only companion is Dolores, a giant Pacific octopus who also happens to be Ro's last remaining link to her father, a marine biologist who disappeared while on an expedition when Ro was a teenager. When Dolores is sold to a wealthy investor intent on moving her to a private aquarium, Ro finds herself on the precipice of self-destruction. Wading through memories of her youth, Ro has one last chance to come to terms with her childhood trauma, recommit to those around her, and find her place in an ever-changing world"-- Provided by publisher.
