The quantum garden
(Book)

Days ago, Belisarius pulled off the most audacious con job in history. He's rich, he's back with the love of his life, and best of all, he has the Time Gates, arguably the most valuable things in existence. Nothing could spoil this...except the utter destruction of his people and the world they lived on. To save them, he has to make a new deal with the boss he just double-crossed, to travel back in time and work his quantum magic once again, tracking down the source of the wormholes.
