We all have different taste in books and that's a beautiful thing! I'll be using goodreads' rating system as reference...
***** 5 stars: it was amazing!/ page turner/ I would read it again!
**** 4 stars: really liked it/ maybe I'll read it again
*** 3 stars: liked it? Well... I didn't liked it but I didn't hate it
** 2 stars: it was ok/ could do better
* 1 star: did not like it at all/ *sigh*
