Ok, I've started! Based on J.Vo's recommendation, I continued my book offensive with a quick read of Griffin & Sabine. Her review was short and highly accurate: "Griffin and Sabine will take you 45 seconds and is totally awesome. Or at least it was when I was in high school." Ok, it actually took me about five minutes, but yes, I read it 15 years too late. I think I would have thought the love story and melancholy and whatnot were all very deep when I was in high school; today, I'm giving it a big old "eh" with a healthy dose of eye-roll. The art, however, is lovely. If anyone wants to spoil the rest of the trilogy in the comments, feel free.
Next up: Everyone seems to think I should read Assassination Vacation. I expect this one to take a bit longer.
