All the Lovely Bad Ones Graphic Novel: A Ghost Story (novel by Mary Downing Hahn) and adapted by Scott Peterson, Naomi Franquiz, Brittany Peer and Joamette Gil is probably my favorite of the novels by Hahn turned graphic novel. And their Wait Till Helen Comes was always a favorite book, so you’d think that adaptation would be my favorite, but there was something about this one that captured me. It probably was because Helen had been a favorite, and therefore, nothing lives up to it, and also that one felt a bit dated, where this one didn’t. It had a few bumps (the timeline felt a smidgen forced) but otherwise it worked well.
However, there are a few issues such as talk of suicide, death of children and abuse. But nothing is overly graphic and all is handled well. Despite this and the “spooky” nature of the “bad ghost” things are really very mild. Still, it is not for the sensitive reader, but at least 10 and up should be fine (younger if a strong reader). I don’t want to tell people not to read this book, as I adore Hahn as a writer (I mean, I have since I was a kid) but she is not for everyone. 
The artwork is well done and captures a classic feeling without being dated (I had to check that this was not one done back in the 1980s or early 1990s; as it is classically Hahn). The adaptation is fun and allows the modern reader to get into things. The illustrations work well for the story and the modern look keeps you in the moment as you follow the brother and sister pair with their pranks and then ghost hunting/fighting.
The story is 101 Ghost Story: two siblings come to stay the summer with their grandmother at her inn in Vermont. They hear the stories that the place was haunted and decide to cause mischief (their specialty) that will get out of hand as it wakes the real ghosts. And then, the siblings must stop the evil. If you have read Hahn or any ghost/thriller story, you know what is happening, there are few real surprises. If this is your first time, you’re in for a treat and some tricks.
