"Miguel Rivera's debut novel is a layered treatment of redemption, purpose, and commitment. Its narrative is often brutal, sometimes violent, and immensely human. This is not a typical fantasy novel. Rivera has shown that new dimensions of time and space do not compromise the collective values that define our humanity. His characters resonate and are memorable. I look for great things from this new novelist, who knows how to infuse a compelling story with suspense, purpose, and wisdom."-Greg Fields, author of The Bright Freight of Memory, PEN/Faulkner Award nominee

"Miguel Rivera's fast-paced, gripping narrative draws the reader like a powerful magnet. How could one resist 'Dee' DiBenedetto, his young, very attractive heroine, born in a law-enforcement family, who likes martial arts and boxing? . . . Ironically, unexpectedly, Rivera mischievously enjoys moving our expectations out from the detective trope just to open up new dimensions, offering turning-point surprises that will show why Darlene is a spectacular, larger-than-life character. Where does Darlene really come from? What destiny must she fulfill?

"Philosophical sci-fi at its best, Pivotal Universe will certainly open up one's mind-literature as the ultimate technology to enlarge one's mental screen."-Heloisa Prieto, Brazilian award-winning, bestselling author of The Musician

"Miguel Rivera is a gifted writer with an incredible imagination. Pivotal Universe brings us into a world quite different from our own and leads us on a wonderful journey. Great read, highly recommended."-Angelina Kelly, Inkslingers Writers' Group
