In a world ruled by machine gods, a fierce catboy and trouble magnet gets caught in the crossfire between several opposing factions, which leads him to a handsome man with mysterious ties to his past and on a quest to regain his missing memories.
Summarizing ZDJJ isn't the easiest task, there's just so much happening in this cyberpunk-inspired novel. T97 knows her genre and clearly has a lot of fun dabbling with its tropes. While the novel's world is bleak, she takes a very playful approach to both world building and plot development, resulting in a frenetically paced adventure leading our boys from virtual realities into their own minds and into the past.
Running through the story is a strong current of "fight the fucking system(s), power to the people", earning the punk in cyberpunk - and no matter how many detours it takes, this being a book by T97 means everything comes together beautifully in the end.
The real highlight are the characters, though. Su Heting, MVP of the prequel Time-Limited Hunt, is an enjoyable protagonist: smart, strong, a skilled liar and conman, rebel extraordinaire. Maaaaybe he's a tiny bit OP, but he makes up for that by his unique talent for getting into trouble. Never a dull moment with the cat - much to Xie Zhenshu's misery.
XZS for his part is a real yearner; there's one single braincell rattling around in that head of his, and it keeps going "cat cat cat cat cat" ad infinitum. He's the quietly intense counterpart to Su Heting's flirtatious, shameless nature. They complement each other well.
Both young men come from a loveless childhood, were tools more than kids, and they fall for each other quickly. Likely due to tightening censorship, they can't be as horny as previous T97 couples, but there's no doubting the absolute love they have for each other.
The side cast is huge and varied; a bit too huge to develop everyone equally well, but most of them get a moment to shine (especially on the Thai covers; didn't expect the Monk to look this sexy).
Although T97 said both books can be read as standalones, I do recommend reading Time-Limited Hunt before ZDJJ. A lot of things will make more sense this way, and it's also fun to recognize certain characters and to see what kind of role Su Heting really played in the prequel's events.
