Really enjoyed the first book. Started questioning things in the second. By the third, I was hate reading it to get to the end.
Without spoiling it, the ending completely failed to land for me. Just a hodgepodge of incomplete ideas and loose ends... If it was just the first book they could've told other stories and built a Lovecraftian mythos around it, but instead they had to go for the 3 book deal and by the end it was just too much toast and not enough butter for me.
