Queens of Geek (by Jen Wilde)

A fun YA that is very much a love letter to geek culture. Three best friends attend the ComiCon-esque SupaCon and have various adventures. One is an out bisexual YouTube star trying to avoid her ex-boyfriend and dealing with a crush on a fellow YouTuber. One is a "big name fan" who is socially anxious in real life (and also in love with her best friend). The third is the aforementioned best friend, who is supportive and nerdy and kind of dreamy.

I loved the feminist sensibility, the diversity, the focus on the female characters.  (Only Tay and Charlie, the two female characters, get point of view chapters.) (All three main characters also have gender-neutral names, which I found interesting.) Clearly Jen Wilde is intimately familiar with fandom and fandom culture, and it shows. Highly recommended for YA fans and nerds!
