It's terrible. This had never happened to me while reading a book before, but I ended up doing a mental fancast for the main characters of You & Me by Tal Bauer. Don't judge my mental fancast too harshly, because I'm absolutely convinced by it.
Swann Arlaud as Luke Hale
Colin O'Donoghue as Landon Larsen
Britain Dalton as Emmet Hale and Dylan Arnold as Bowen Larsen
As for the book itself, it's a lovely love story between two men in their forties, as well as a beautiful story about fatherhood. Anyway, it's really great, and if you can : read it.
I've rarely loved a love story as much as this one. Everything feels so natural, and they communicate so well. I also love seeing adults who are already well established in their lives fall in love. The characters are incredibly endearing, and this is definitely the kind of book I'll read again.
