In the book there is a Spanish story with parallel translation into English (the Spanish text is on the right, the English text is on the left). It is recommended to a wide range of people studying Spanish, starting from the level A1: you must be able to read in Spanish. I recommend to practice reading skills, learn new words and idioms for the beginners. At a higher level, you also need to retell the content close to the text. The book contains 1127 words and idioms.
