Hearthkeeper - Cordelia Kingsbridge An excellent AU from Cordelia Kingsbridge with some great world building. 'Hearthlighters' are firstborns and considered superior to their spouses, the 'Hearthkeepers.' Jules doesn't fit the mould for a hearthkeeper and wishes for more fulfillment in his pampered privileged life. This comes in the form of Keaton, a GIS agent, who blackmails him into spying on his husband Henry.
