The Red Ledger: 4 (The Red Ledger #4) by Meredith Wild

OMG so enthralled in this story I almost screamed when turned the page and it was the end. Tristan and Isabel are becoming much closer as the time goes on, they are still in grave danger; but they are working together to bring the organization down.
Tristan is learning more about his past and have more memory flashes, while Isabel learns more about her family and their roles in all of this.
Can't wait for the next installment to find out where this all is going to take us and how it will affect all of the characters.
