Code Mages & Empty Pages by Rhea Fox

Dawn just wants out: out of her empty house, out of her writer’s block, and out of excuses. Taking a new admin job at Frostfire Real Estate isn’t exactly her dream, but anything is better than staring at a blank page. She knows she has another book in her—now she just needs the red thread to pull it together.
When a structure-eating fungus takes over her hallway cupboard, everything seems lost. Then her colleague Luc offers his guest room, and suddenly Dawn finds herself in a slow burn, roommates-to-lovers situation she never expected.
Lucien Atkins joined Frostfire’s IT department for a fresh start, trading in his old life for something quieter. But the new team assistant glitches his carefully coded boundaries. Between barefoot cooking, late-night gaming, and the fairy cat he insists Dawn adopt, Luc realizes that hurt and comfort can coexist—and that the woman sharing his space might be the one he wants for good.
