My book club just read 'The Storied Life of AJ Fikry' by Gabrielle Levin and we all loved it! I agree with The Invisible Bridge and the ken Follett books too. My three favorite authors are Pat Conroy, Geraldine Brooks and Nelson DeMille---anything written by these three are superb books. If he likes non-fiction, I highly recommend 'The Boys In the Boat" and "Unbroken"--both are really really good.
