Eggers and Frey (AHWOSG vs. Million Little Pieces)

So I'm reading A Heartbreaking Work of Staggering Genius and I can't help but notice the similarities between the stylistic (and even some of the content) elements between this book and Frey's A Million Little Pieces.

Now, after everything that's happened, it's clear that Frey might've ripped off this style from parts of Eggers's memoir. But where Eggers is overly honest about what he's writing and what really happened, Frey is not.

Has anyone else noticed this? If you have read both books, please let me know if you noticed any of these similarities.
