“You finally came to see me.”
This book builds heavily off of past storylines and exclusively features previously introduces characters. At least books 3 (Book Girl and the Captive Fool) and 4 (Book Girl and the Corrupted Angel) must be read first, though it’s best to start at the beginning (Book Girl and the Suicidal Mime).

Here we go. The past that has haunted Konoha throughout the series comes to light in an incredible roller coaster ride of emotion and angst. Torn between the friends of today he finally made and the tragic events of yesterday, Konoha will have a lot of hard truths to face about himself and others.
It would be a disservice to this book and the ones before it to get into any real details. Book Girl and the Wayfarer’s Lamentation is an absolute masterpiece. Extremely hard to read in parts because of the raw emotion our leads are dealing with, but more than worth the effort. Everything from the way the chosen literary parallel is used to the resolution of several long running plot threads is pitch perfect and has tremendous impact. I hated certain characters, cheered for others, and wanted to shake sense into some so much at certain points I felt like screaming.
In a lot of ways this seems like the culmination of the series, but a chilling closing line reminds us that there are more mysteries to explore before the end.
I can’t praise this series enough.
