Super-Short Stories for English Learners is an enjoyable collection of very short stories that English/ESL learners (or anyone) will love, ranging from adventure, to love, to horror. There are several books, each one for a different level of English learner - from beginner, to intermediate, to advanced. This series grows with you as your English improves. 

Each delightful story (depending on which level of book you choose) is between 500 to 1,500 words, so you'll easily be able to read while on the go (during your commute, while in line, during those found moments and short breaks throughout your busy day). The more you read and re-read, the more you'll reinforce your understanding of vocabulary and grammatical elements. The best way to learn vocabulary, in fact, is to read. Never study vocabulary lists. Instead, read interesting content that you enjoy. That is the only way to learn and be able to use vocabulary correctly and in a native way. And before you know it, you'll level up your English!
