The Last Kind Machine - A Hopepunk Mystery of Secrets, Second Chances, and the Machine That Remembers What We Choose to Forget

He kept one secret locked behind a door in his own workshop for three years. She finally found the key. Widowed and quietly grieving, Mara Voss has spent three years letting a locked door in her late husband's workshop stay locked, telling herself it's easier that way. But when a dead soldering iron finally sends her looking for a spare, what she finds behind that door isn't spare parts. It's something the law says should never have existed at all - something her husband hid from her for reasons he took to his grave.
Now Mara has to decide how far she's willing to go, and how much she's willing to risk, to finally understand the one truth about her marriage she never got to hear. But she isn't the only one who knows what's hidden in that workshop - and the people coming to take it don't care what it means to her, only that it's found. As the clock runs out on all sides at once, Mara is about to learn that some secrets weren't built to be kept forever, and some doors, once opened, can never be closed again.
When the truth is finally close enough to touch, will she reach it in time - or will it be silenced before she ever gets to hear the words her husband spent a lifetime too afraid to say?
