The first book in Bonnie Dillabough’s Dimensional Alliance series, and the book with which she became a novelist at sixty-three. A tribute and a review.
Every series has a first door, and for The Dimensional Alliance it is a literal one: an impossible door in a strange little house on Infinity Loop, opened by a key that fits nothing in the ordinary world. The House on Infinity Loop is where Bonnie Dillabough’s whole multiverse begins, and it is where Bonnie herself began as a novelist, publishing this first book two weeks before her sixty-fourth birthday. Both beginnings are worth honoring.
The setup is pure invitation. A young woman named Jenny inherits the house from her aunt, and with it a cat who is not quite a cat and a tiny key on a gold chain. When the key opens a door that should not exist, Jenny steps out of the workaday world and into the realms of the multiverse, and finds, as the best portal stories arrange it, that the fate of everything she loves now rests in her hands.
A doorway, in fiction and in life
It is hard to read this opening without thinking of how it came to exist. Bonnie had carried a recurring dream since she was sixteen, a story waiting decades for her to write it, and she finally crossed her own impossible threshold late in life, sat down for a NaNoWriMo challenge, and wrote seventy-eight thousand words in a month. The book that resulted is this one. The parallel is almost too neat: a story about an ordinary person discovering that a door has been waiting for her all along, written by a woman who discovered the same thing about herself at sixty-three.
In memory
A tribute to Bonnie Dillabough — the friend, mentor, and author behind The Dimensional Alliance, in her own story and mine.
What the book sets in motion
As a series opener, The House on Infinity Loop does the foundational work of establishing Jenny, the house, the key, the cat, and the multiverse beyond the door, the architecture every later book builds on. The tone Bonnie set here would carry through all eight volumes: sincere rather than cynical, warm rather than grim, built on the conviction that an unremarkable person can rise to meet a destiny she never saw coming. It is a kind, hopeful kind of science fiction and fantasy, and that kindness was Bonnie on the page.

It is never too late to write the book inside you — Bonnie published her first novel at sixty-three. Proof that the door is always still there.
How the book came to be
The origin story is worth telling because it is as improbable as anything in the novel. Bonnie had spent a lifetime writing other things, songs, poetry, church plays, marketing copy, decades of work online and in broadcast television, but she had never called herself an author. The dream of this book had lived in her since she was sixteen and stayed unwritten for nearly fifty years. What finally moved her was an interview she worked up the courage to request with Mercedes Lackey, one of her own heroes. When Bonnie admitted she had always wanted to write a novel, Lackey gave her the plainest possible advice: put your butt in the chair and write. Bonnie took a NaNoWriMo challenge, wrote seventy-eight thousand words in a month, finished the manuscript on New Year’s Day, and published it that spring. The House on Infinity Loop is the book that fifty-year wait produced.
I had the privilege of nudging her toward that keyboard, and watching her step through her own impossible door and build an entire universe on the far side of it remains one of the most rewarding things I have witnessed in this work. This first book is where it all started.
