No Apollo-G Necessary by TL Reeve

Apollo Abaeus has been many things in his life, a doctor, scientist, philosopher, and a Pinkerton, but as the years have rolled on, he’s lost his zest for life. When a letter arrives six months later than it should—thanks to his conniving sister Artemis—announcing he has an eighteen-year-old son—AJ Delphi—in New Haven, Washington, he drops everything to meet the boy.
Violet Beckett leads a chaotic life. As the mother of twin teenage sons, Finn and Seth, she’s used to running a tight ship, until he shows up in her life and turns everything on its head. Apollo is attentive, gracious, and patient. He has a knack with kids and also offers to help her sons’ band.
However, Violet is missing something. She just can’t put her finger on what it might be. He’s just too good to be true or real.
When the truth comes out about who Apollo is and his connection to AJ, will Violet and Apollo’s budding relationship survive? Or will the woman he’s convinced is the one, become just a name on a long list of ex-lovers?
