Our main gal here is an eleven-year-old yankee kid named Sibby, living up in Massachusetts. She’s poking around a creepy, empty old Victorian mansion down the road when she looks through a window and spots a real nice library. Being a curious little thing, she breaks right in. But when she tries to step back out the door to run home for supper, the backyard is gone. She’s standing on a total stranger's seashore in a completely different dimension called the Otherworld. Now, this ain't a friendly neighborhood. The place is a giant, confusing gumbo of old Greek myths, Celtic fairy tales, desert nomads, and—I kid you not—a live brontosaurus just roaming around. Luckily, before some swamp monster can eat her alive, Sibby gets picked up by a band of traveling adventurers. The leader of the crew is Prince Leron, a heroic fellow who has pledged himself to a massive, life-or-death quest. They’ve also got a wise old blind prophet named Arbytis taggin' along. Turns out, the neighborhood is being terrorized by a real piece of work called the Deathless Queen of Treclere (who goes by Simirimia). This Queen is using dark sorcery to control the whole land and has locked up a poor Princess in a glass tower on an island. Leron and his buddies are on a mission to knock the Queen off her high horse, rescue the princess, and save the day. Sibby just rolls up her sleeves, joins the party, and realizes she has to find a whole lot of inner grit and spiritual backbone just to survive the road trip. They go see oracles, get their fortunes told, and fight all kinds of crazy creatures. By the time it’s all over, Sibby helps them win the day, learns a shocking secret about who she actually is, and slips back through the window into Massachusetts right at the exact second she left, like nothing ever happened. It's a mighty fine yarn. It starts a little slow and the world-building is thicker than cold molasses, but once the quest gets moving, it’s a real classic "kid falls into a magical world" adventure.
