The book is Is That a Word?: From AA to ZZZ, the Weird and Wonderful Language of SCRABBLE:
Scrabble® aficionados may know that both "Brr" and "Brrr" are legitimate plays, but what about everyday names like Peter, Carl, and Marge? They're not listed as proper nouns, but they are certainly playable. For lovers of Scrabble®, Bananagrams®, and Words with Friends®, this lively guide helps readers make the most out of word games, packed with new ways to remember the best words alongside tips for improving game play and much more. Part strategy guide and part celebration of all things wordy, this collection of facts, tips, and surprising lists of playable words will instruct and delight the letterati.
For example, the book has a handy list of playable comic book characters:
