Her Majesty’s Swarm (2020)

Blurb:
A young woman, net nickname Mushi-nee, finds herself sucked into a world, not unlike the online real-time strategy game that was her only escape. She had captained the “Arachnea” faction … but it’s one thing to do on a computer, and another to find herself face-to-face with giant arachnids who hail her as queen! But rather than shrink from her fate, she steps up … to become the conquering queen she knows she can be!
