Here's the list of Movellas I've read that I recommend.
1. Erased by Yulinda. A story about a girl named Sophie in a dystopian future. An overpopulated future. To get rid of the 'weak' people, the government (possibly an oppression) decides to do a 'survival-of-the-fittest'. If you're tagged, meaning you're weak, you're to be erased. When Sophie gets tagged, she must do what she can to survive. A great thriller. Read it if you're a fan of 'The Hunger Games', 'The Purge', 'Divergent', and 'Terranova'. It's amazing. 5 pens out of 5.
2. Rogues and Renegades by Aunt Midnight Rogue. A fantastic story that explores two dimensions. A unique plot you won't find anywhere else. Jumping between two dimensions taken to a whole new level. Only thing I can say; read it. 5 pens out of 5.
