The divergent series was great. I hated the ending, but it had to end somehow, but why would you make Tobias fall in love with CHRISTINA, Tris's best friend out ALL PEOPLE. The epilogue to Allegiant was like a stab in the chest, and this book was a straight up stab right into the heart.
And anyway, why would you spend the entirety of 3 books building but Tris and Tobias's relationship, and then kill her in the ending?!! And as if that's not bad enough, you make him fall in love with her best friend, and write ANOTHER book without Tris in it at all. That just erases Tris's importance
