I'm always impressed by any author who can write an amazing story in less than 200 pages. I'm usually disappointed by novellas and anthologies because the stories are just too short to really draw me in the way a full-length novel is capable of. But there are always exceptions and with Anne's help I've listed some below.
Genesis (Stand-Alone Novel) | 150 pages
Silver Shark (A Kinsmen Novella) | 106 pages
The Strange Case of Finley Jayne (Steampunk Chronicles Novella) | 83 pgs
Super Bad (Superlovin' #2) | 133 pages
