This is Us book titles

Anyone know what books were in young William's bookshelf on the show This is Us?Don't remember which episode it was,but it was when Mandy Moore's character met with her adopted son's biological father and showed his bookshelf and all the books he had.The only one I could remember was Poem Counterpoem,I think it's called.Any help would be MUCH appreciated!
