Based on two decades of research, The Late Devonian Mass Extinction reviews the many theories that have been presented to explain the global mass extinction that struck the earth over 367 million years ago, considering in particular the possibility that the extinction was triggered by multiple impacts of extraterrestrial objects.

I gave this book four stars instead of five because it is written for the advanced student rather than the average reader like me. The book is curiously inconclusive. The evidence of cause sits so far back in time the cause of the extinction is fuzzy as best. Large meteors seem to fit the bill but the evidence for this is still a work in progress.
