The Heart's Husband. The Hidden Library, #8

Forgotten But Not Gone If Wynne didn't love his husband and their daughter so much, he would walk out of Lord Hathaway's mansion and never come back. Damned lilies were making him choke. And die. But when the sudden allergy turns out to be spells cast to make Wynne forget his own past, the threats against him and his beloved husband turn deadlier than anything Wynne has ever known. Somehow, he must find and stop a God-Mage who absolutely controls memory itself. .before he has to sacrifice everything to save the ones he loves.
