I don't think I will remember any of the stories in a year, they are all sort of mediocre fiction that a high school student might have written for a class assignment in creative writing. But 'graded readers' are edutainment — they are structured in a way that they can reinforce what you know and help you understand phrases and grammatical patterns through repeated exposure. The stories don't need to be good, they just need to be good enough to keep you reading. And they are, here. I'm going to go get the Intermediate level in this series!
