Help! My Wizard Mentor Had a Heart Attack and Now I'm Being Chased by a Horde of Giant Spiders!

Patrik Conroy has just been dragged through a portal to a magical universe that operates like a video game. Apparently, some wizard thinks he's destined to save the world.
There's just one problem.
The wizard didn't live long enough to tell him what he needed to save it from. Or that the resident giant spiders were friendly and just looking for a hug. Now the spiders are dead, the local villagers have lost their only source of income, and Patrik needs to pretend he doesn't know how all this happened.
A tall order for a community college student in his fifth year of a three year degree, who hasn't played a video game in over a decade.
