What happens when you kill the monster but inherit its lair?Gabriel escaped his abuser by killing him and wants nothing from the wreckage left behind. Not the cursed manor. Not the noble title. And certainly not the corrupt aristocracy demanding he toe their line.But this is Averdon, where the dead can cause just as much trouble as the living.Gabriel's inheritance makes him legally unable to marry Miles, the mage who saved his life and the only one Gabriel refuses to lose. Miles is determined to help him walk away from it all, but Rookgate Manor refuses to let its new master go. To claim a future together, Gabriel and Miles must return to the city that broke them and pit their blades, spells, and most outrageous schemes against those who oppose them.Gabriel has one choice left: destroy the monster's power forever or remake it as his own. Preferably before his taxes are due.This witty, high-heat M/M gaslamp romantasy features a ride-or-die power couple, found family, and a haunted house with opinions.Err Apparent is the first book in the Tenibrian Affairs series, delivering gothic atmosphere, banter-rich romance, and emotionally grounded spice. With an HFN, this is perfect for readers who enjoy the quasi-historical fantasy of Freya Marske, KJ Charles, and Jordan L. Hawk, paired with the trauma-aware relationships and explicit heat of Foz Meadows, Lily Morton, and Tavia Lark.
