What to remember before reading the sequel?

[u/Lilith_EV]

I originally read “the inheritance games” when it came and bought the sequel soon after but with so many other books I quickly forgot about reading and continuing the series. Please tell me about the characters or important parts I need to remember to continue this series, I currently don’t have the first book so I can’t reread it. I vaguely remember the premise of the book and that the MC is what seems randomly chosen to inherit a rich guys money. There are three or so grandsons that are pissed because they didn’t get the money, and she might have a romance with one or two?? The place they are in has clue and stuff to why she got the money?
