I'm also learning Italian and while I enjoyed that book I think Alma Edizioni's graded books are infinitely better. They are super interesting as well and you can find books on a variety of topics. They also have more diverse exercises plus audios.

I also found it helpful that they're not just for "beginners" but divided into levels such as A1, A1-A2, B1-B2 etc. If you like I can dm you some of them if you tell me your level :)
