61g5izigvVL._SL160_The Riverman by Aaron Starmer isn’t a GU book, but it deserves a mention here – and not just because it was so unique and riveting that I was literally unable to put it down, and read it all in a single sitting last night. It isn’t a GU story – but it’s the story of a GU companion, essentially, and provides an interesting perspective on that role.

Alistair, 12, gets a visit one day from a childhood friend, Fiona, who tells him an unbelievable story. Since the age of four, she has been visiting a magical otherworld called Aquavania, where everything is created by the imagination. But there is a sinister threat – a figure called the Riverman has been invading children’s self-created worlds there and sucking out their souls. Fiona fears she will be next.

Alistair never journeys with Fiona, and for most of the book he is doubtful that any of her story is real – assuming instead that it is a cover for a more mundane but still awful trauma. But as things escalate, the horrible truth of the Riverman is revealed, and Fiona disappears, leaving Alistair to figure it all out. I can’t really say  more here without spoiling it, and this is a book that hinges on the mystery, so I will leave it at that.

But what fascinated me along with the plot was to read a first-person narrative by a Girl Underground’s companion, to see him as a protagonist in his own story, with the Girl’s adventures being only related second-hand, and taking a secondary role. And there is no doubt that Fiona is a Girl Underground – the author’s website even gives this description, linking her with several other GUs:

“Fiona Loomis is Alice, back from Wonderland. She is Lucy, returned from Narnia. She is Coraline, home from the Other World. She is the girl we read about in storybooks, but here’s the difference: She is real.”

While I felt that this book stood on its own even with a somewhat unresolved ending (not everything, after all, needs to be neatly tied up in reality), it turns out there are two more books planned, and I will have to give them a shot despite my skepticism about series, since this one was so engaging.
