This latest from Dade ("There's Something About Marysburg" series) delves into the world of fandom, in which superfans attempt to wield the weapon of fanfiction to right the wrongs perpetuated in a universe that has jumped from book series to TV show. Geologist and cosplayer April (aka Unapologetic Lavinia Stan), and actor and secret fanfiction author Marcus (aka Book!AeneasWouldNever), are good friends in the online community dedicated to shaping the wildly popular internet couple Aeneas and Lavinia. What no one in the fandom realizes—since it could cost him his job—is that Marcus is Aeneas. Or at least, he plays him on TV. When April's latest plus-size Lavinia costume goes viral, Marcus asks her out to dinner to quiet the internet trolls but soon figures out their virtual connection. He can't admit who he is online, but that's not the only thing he's hiding, and April is immediately suspicious that the Marcus the world sees is nothing like the real man. Can a relationship begun online survive in real life? VERDICT Even those new to online fanfiction will find this a charming and engrossing read. Issues of body positivity, dyslexia, and found families are among the topics addressed with sensitivity and realism. The between-chapter segments of fanfic server chats, fanfic synopsis, and truly horrible screenplays add to the fun.—Rebecca Moe, Alden Ewell Free Lib., NY
