Redemption is book two in the Catherine Kimbridge Chronicles, which follows the story of the genius whose name graces the series. And I use the term genius literally, not sarcastically. At times to the detriment of the narrative in the first book, making Catherine the singular hero of much of the first story.
This is where the second book excels where the first book fell short - while Catherine Kimbridge is still central to the story, she no longer is the only person contributing to solutions. Here she is still a bit too much to be real, though she no longer is the only starring character and no longer the soul hope of humanity.
Readers of the prior book will (hopefully) be pleased to see some familiar characters return to the story including Ben.
Overall, the book is an enjoyable read, though in the edition I read it still needs some editing for typos and the like. Fortunately, with Kindle editions it is possible for the author to correct these issues and push out revisions for the next read-through.
