As a teen, I loved the Blue is for Nightmares series. 
 Okay, who are we kidding- I still love it today, even though my book preferences have changed a bit since then. 
 I like all the characters, although Drea is slightly irritating. I have to admit, even though their relationship is more backseat to Stacey's and Jacob's, Amber and PJ really are just the cutest jar of jam. 
 Black is for Beginnings is a quick read- 160 pages, but it's all in comic form which is quite a turn from the first four books. Because of that, the beginning of the book was slightly disorienting, and I was unsure at first. 
 Once I got into it, I didn't mind the comic form. It made it really quick, and definitely finalized the series after I had been wanting to know what had happened after book four for, I don't know, 7 years. 
 Yeah, seriously. Seven. Years. 
 -pauses to have a age crisis- 
 Anyway. 
 I enjoyed Black is for Beginnings and I'm happy with it and the series overall. I do wonder why the author decided to change the format, but I actually liked it because it revisited the past but then tied the end together.
