Would you fight for a love that feels right, even if it’s for someone you’ve never met? Not because you don’t want to, but because time has separated you by 6 months? Sounds crazy, right? But that’s what happens to Tressa Fay Robeson in Cosmic Love at the Multiverse Hair Salon.
Tressa Fay is a successful and popular hairdresser known for giving her clients life-changing hairstyles. She is still recovering from a break-up when a random text message sends her across town on a date, only to be stood up at the bar. Well, not exactly stood up. Her date tells her where she is, but they aren’t there. And they didn’t stand each other up. They were both at the bar. It’s just that Tressa Fay is in the present and her date (Meryl) was waiting for her six months ago. Tressa Fay tells her friends that she’s texting a hot woman in the past, and they believe her.
From there, you and the characters enter a trust bubble. You have to trust that Meryl and Tressa Fay can communicate via text as the characters do, and believe that it’s really happening. We spend the opening section of the book focusing solely on Tressa Fay in the present. This shows us that, in the past, Tressa Fay hadn’t met Meryl and confirms she wasn’t supposed to. But Meryl doesn’t want to be trapped in a future where she disappears and doesn’t get to love Tressa Fay, even if it has consequences.
I think Annie Mare does an outstanding job not only of bouncing between timelines but also of guiding the reader through complex scientific concepts. Mare navigates them expertly because she’s hyper-focused on the emotional connections shared by all the characters.
This is Mare’s and the book’s strength. She was happy to hold my heart in her grip. I cared about all of their futures with all my heart. I teared up, held my breath, and crossed my fingers for the right things to happen.
But the science isn’t the driver of the story; the driver is two people who are passionately in love, desperate to meet and desperate not to lose each other, but it’ll only happen if they play the science right.
With seemingly nothing to lose but everything to gain, they start messing with time.
All their pasts and futures become tangled; their connections are so tenuous because the present could be changed, and they could be severed from each other at any moment.
They have the power to tell Meryl her future, and I kept wondering which upcoming past event they would choose to change and how it would manifest in the present. This tightened her fist around my heart like a vice for almost the entire time.
It’s a hard premise to land — how much of the mystery do you explain? Do you go where the readers expect, or where you expect? I think the concept for resolving the overlapping time was masterful; I was expecting one last dramatic revelation, and it didn’t come, and what happened as a result didn’t work for me.
Mare, I think, wanted a specific tone for the ending, but instead of leaning into the danger of their experimentation, she played it too safe. All the tension I had been holding slipped away, leaving me slightly deflated.
Cosmic Love at the Multiverse Hair Salon, to me, is a meditation on the nature of love. The story itself feels like an instructor. I was its student. Because Meryl doesn’t want to be trapped in a future where she disappears and never gets to love Tressa Fay, every observation felt like something I needed to study and hold onto. There were so many observations I felt compelled to write down to study later. I loved watching them and taking notes as I explored, changed, loved and laughed — I just can’t promise you’ll like the last few pages.
Recommended for anyone who enjoys (or thinks they’ll enjoy) a mix of sapphic yearning and science fiction.
Note: I rate on a four-tier scale: Loved (4.5–5★), Liked (3.75–4.25★), Mixed (2.75–3.5★), and Not for me (1–2.5★).
