These are all STAND ALONE BOOKS. They can be read in ANY ORDER, it doesn't really matter.
Newbies to these books are advised to start with HERO if you want to follow the time in which things happen. But again these books are STANDALONES and can be read in any order, just know you will jump around in time.
This is the love story of Josh Faraday and Kat Morgan. Kat Morgan is the sister of the Morgan brothers (Colby, Ryan, Keane, and Dax from standalones HERO, CAPTAIN, BALL PEEN HAMMER, and ROCKSTAR). Josh Faraday is the twin brother of Jonas Faraday from THE CLUB TRILOGY. But you can jump right in and read Josh and Kat's trilogy first!
This is the love story of Jonas Faraday & Sarah Cruz.
The Culmination, is in “the future" and is from Jonas & Sarah’s POV. This book also features Josh Faraday and Kat Morgan in the future. Readers are advised to read The Culmination AFTER both trilogies to avoid spoilers.
