Outland

OK, it is now settled. I will read (or as in this case, listen to) anything by Dennis E. Taylor. He provides that perfect mix of nerdiness, action, characterization, snark, and world building that appeals to the SF fan in me.
In Outland an eclectic group of university students in Nebraska discover how to create stable inter-dimensional portals. They include a Newton/Einstein level genius, a geologist, an uber engineer, and several with more, um, “practical” skills.
They discover an alternate and almost identical Earth but without any humans. So what do you do in such a case? Why you go panning for gold of course. After all, you need to funds to protect your world-changing discovery from poachers and from takeover by government organizations. Naturally, things don't go exactly according to plan. First, some criminal elements figure out that they are on to something, and then the Yellowstone super-volcano comes to life. From that point, things get very exciting and complicated. Big decisions have to be made. Can this alternate Earth be their key to survival? Read to find out.
Good story. 4+ stars.
