I'll lean on a bit of propositional logic to keep things brief, beginning with common misconceptions that I (if only subconsciously) have fallen prey to before:
Book A is about teenage girls ⊨ Book A is for teenage girls
Use of twisted teenager trope ⊻ Creative, layered, mind-bending
Megan Abbott makes the above statements patently false. While I hope to give this the review it deserves when time allows, for now I will propose a working thesis that should be taken as praise of the highest order.
Megan Abbott : the world of teen girls :: Dennis Lehane : South Boston
