Ryan Kaine’s Origins is the companion series to Kerry J. Donovan’s main Ryan Kaine’s 83 action thriller line. While the 83 series follows Kaine’s story in a straightforward sequence, Origins fills in the gaps with backstory, prequel material, and scenes told from different characters’ perspectives.
The series includes The Assessment, which stands alone as an original Origins entry, alongside companion versions of many books from the main series. These companion editions expand on events from On the Run, On the Rocks, and other 83 novels by showing what was happening behind the scenes or from another character’s point of view.
Readers who enjoy the main Ryan Kaine series will find that Origins adds depth to the characters and plot threads they already know. The books work best when read after the corresponding 83 entries, though The Assessment can be read on its own as an introduction to Kaine’s military background.
