You Are Summoned. A LitRPG Adventure (en Inglés) - Dean Henegar

It was supposed to be another boring day at the insurance office for Rico Kline, but powerful forces had other plans for him.

Finding himself repeatedly summoned to other worlds as a disposable minion, Rico must face deadly foes, disarm insidious traps, become a test subject, and run the occasional errand for his various summoners.

At least when each summoning is over, he's rewarded and sent back home. But being back home has its own set of problems, and he'll need to grow stronger to face it all.

Bestseller Dean Henegar returns with this unique spin on isekai LitRPG, about a MC turned into a summon minion who has to complete tasks for random summoners, allowing for a variety of adventures, foes, and missions as he progresses in power each time... But is any of it random?
