Book Recommendations

Looking to get back into reading about Columbine. Does anyone recommend any books about Columbine? Does anyone know if any one has done more highlights about the 11k file or if anything stands out to them?

Thanks in advance!

Jeff Kass's Columbine book's the best one out there imo. There's also "A teenage philosophy of awareness and existence" by Mathijs Koenraadt, focuses more on Harris and Klebold's worldviews in a more philosophical standard rather than the typical "This passage was indicative of *insert mental illness here*" line you get from most other books.
