Towerbound

Over 100,000 reads on Royal Road. 4.7 on Amazon from 99+ reviews. #1 New Release in Time Travel Fiction. Top 10 in Time Travel Sci-Fi. Towerbound is the Progression Fantasy LitRPG readers can’t stop binging. They left him for dead. Now he’s back—and he’s bringing the Tower down. Ren Varrow was never the hero type. A quiet alchemist with a talent for potions, he kept his head low while others chased glory. But when a top guild lured him into a lethal dungeon and stabbed him in the back, his story should’ve ended. Instead, it rewound.

In Book 2 of the Towerbound series, the Scrap Rats finally have a home base—and a target on their back. Dungeon spawn are shifting, guilds are sending spies, and the in-game economy is breaking down. Ren isn’t a hero. He’s a regressor with a potion empire, a bunch of orphans to protect, and just enough foresight to stay one step ahead.

Book 3 of Towerbound cranks everything up. The Scrap Rats are rising—and so is a world-ending dragon. Ren was just a cowardly alchemist hiding behind potions and excuses. But when a global event drops a world boss into their lap, the guild needs more than a healer—they need Super Ren.

This is a collection of short stories written after each main Towerbound book was published—so for the best experience, listen to Books 1–3 of the Towerbound LitRPG series first.

Here you are, Book 4. You wanted more dragon action? You’re getting it—bigger, nastier, and ready to burn the world down. Ren’s getting richer, Herald’s in the mix, and the District Historical Society just picked the wrong alchemist and professor combo to mess with. Expect more worldbuilding, nastier politics, and answers to questions nobody wanted—like where the hell a gloom sprite even came from. Oh—and mounts are back. Cheddar the Furious, Muenster of War, and Cheezenado lead the charge in a full-on rat cavalry stampede.

Alright, where were we? Let's see… There's a whole bunch of Scrap Rats. So obviously Ren, the cowardly alchemist, who's now become Super Ren, caught in this whole progressive fantasy mess of towers and time travel. Mira, a Cryopyre Mage, who runs the Guild—classic LitRPG fire-and-ice power combo.

These are side quests. Parallel threads. Moments and consequences that don’t fit neatly into Ren’s forward march, but still matter to the world. You’ll see what other guilds are doing. How districts react. What happens in the gaps between major events. Deals made off-screen. Conflicts that ripple outward instead of upward. This is not required listening to follow the core series. You won’t miss plot beats if you skip it. But if you’ve ever caught yourself thinking: What happened to that faction? How did this situation actually play out? Why does the world feel like it shifted here?
