The book contains a set of 8 short stories of different genres (SF, history, slice of life, fantasy, ...). Each story is structured in 3 chapters whereas the chapters contain a summary, vocab, and questions for reading comprehension (solutions are at the end of the book). It uses Furigana throughout the book for about 95% of the Kanji. For my taste, it was too much. Difficult words are marked in bold and are translated at the end of the chapter.

The stories were ok - but it was still engaging to read as you are exposed to different genres. I am at around N3, though I think the book is also appropriate for N4. The reading comprehension questions were good as they helped to enforce the understanding. Overall, good structure. I can recommend it.
