Sin (Aleatha Romig) Books in Order

The Sin series drops into a world of money, power, revenge, and attraction that makes bad decisions feel inevitable. At the center are Donovan Sherman and Julia McGrath, whose story starts with a chance meeting in a blizzard and grows into something much more dangerous.

Julia is trying to make sense of a life that has just cracked open. Donovan is a powerful man who knows how to take what he wants, and who has made plenty of enemies getting there. That imbalance matters from the beginning. So does the chemistry.

These books are set in high finance, but the real pull is more personal than corporate. Donovan's past keeps circling back, Julia is forced to decide what she can live with, and every step forward seems to come with another hidden cost. The tone stays romantic suspense all the way through, with age-gap tension, family drama, and a steady sense that the past is never done with either of them.

Start with White Ribbon if you want the short prelude, then move into Red Sin, Green Envy, Gold Lust, and Black Knight. This is one continuous story, and it works best in order.

If you like rich settings, morally gray heroes, and relationships tested by ambition and revenge, this series leans hard in that direction. The love story is there, but it has to fight its way through a lot of damage first.
