I think this is a continuation of Homesick, but I’m awaiting confirmation from Paul on that. In the mean time, enjoy Web of Life by Paul J. Joseph:
Sally Buds had scarcely arrived on Earth before she is called back into service. She is, of course, Earth’s only real expert on the evil Masters on New Ontario, but now there may be trouble coming from this side of the fold! A Japanese ship representing the Asian Economic Alliance is now heading towards the fold and UN Command fears that they may be trying to forge an alliance with the Masters.
This time Sally’s crew includes a battalion of soldiers armed with deadly weapons. But, as before, the mission turns out to be different than expected. Trapped and a realm that makes no logical sense and defies physics, Sally’s crew encounters an intelligence beyond human reasoning and a beast which stalks them mercilessly seeking revenge for a crime they can’t imagine.
