Series (re)read this summer

There are TWO highly anticipated sequels (3rd Ninth House and 3rd Vicious) coming out this fall and I want to reread books 1 and 2 in the series before they come out. Unfortunately they come out within weeks of each other. If you would like to read or reread the series with me, which order would you prefer doing it in? (because I'm indecisive and can't choose)

OPTION 1
Read Ninth House and Hell Bent First, then read Vicious and Vengeful (likely starting late July/early august)

OPTION 2
Read both book 1's then both book 2's (So Ninth House, Vicious, Hell Bent, Vengeful)

Dead Beat comes out on September 15th and Victorious comes out October 6th
