A Goodreads user asked:
Who else wants to talk about Art? I feel like he doesn't get the attention he deserves. He is such a cool character, and has some of the best lines in the whole book.
This answer contains spoilers… (view spoiler)[I know, right? I think it's remarkable how well he takes it when Wren starts hanging out with Laura. He must have been frustrated that after all this time and all his hard work raising his daughters alone, Laura wants to swoop in and change things. Even more than that, he must have been worried that Laura would let Wren down yet again...and she did, by not waiting for her to wake up in the hospital. Wren didn't expect her to, but I think she hoped she would, which might be why Wren stopped seeing her in person after the event...Anyway, Art had to take care of himself and his two daughters by himself, and it must have been so rough. He's glad that Cath and Wren take good care of each other for when he can't be there, so he was probably really worried when they were fighting. Honestly, Art might be the only character who never annoyed me. (hide spoiler)]
