Sixteen-year-old Bianca Torre is an avid birder undergoing a gender identity crisis and grappling with an ever-growing list of fears. Some, like Fear #6: Initiating Conversation, keep them constrained, forcing them to watch birds from the telescope in their bedroom. And, occasionally, their neighbors. When their gaze wanders to one particular window across the street, Bianca witnesses a creepy plague-masked murderer take their neighbor's life. Worse, the death is ruled a suicide, forcing Bianca to make a choice--succumb to their long list of fears (including #3 Murder and #55 Breaking into a Dead Guy's Apartment), or investigate what happened. Bianca enlists the help of their friend Anderson Coleman, but the two have more knowledge of anime than true crime. As Bianca and Anderson dig deeper into the murder with a little help from Bianca's crush and fellow birding aficionado, Elaine Yee (#13 Beautiful People, #11 Parents Discovering They're a Raging Lesbian), the trio uncover a conspiracy much larger--and weirder--than imagined. And when the killer catches wind of the investigation, suddenly Bianca's #1 fear of public speaking doesn't sound so bad compared to the threat of being silenced for good.
