ZA - do I need to read Ruthless Boys of Zodiac to continue?

[Selena]

Hi, I just finished 3rd book of Zodiac Academy. Do I need to read story with Elise and her boys or can I just skip it?
Or maybe can someone give me the most important things I should know without reading another serie?

Personally, I would! Characters from those books cross over into the following ZA books. The worlds are connected! I was so mad I had to take that break when reading, but I ended up loving those characters.
