-Richard Eder for The New York Times
"The melancholy that hangs over The Solitude of Prime Numbers is seductive and unnerving. A-."
"Giordano's passionate evocation of being young and in despair will resonate strongly with readers."
"The elegant and fiercely intelligent debut novel by 27-year-old physicist Paolo Giordano, The Solitude of Prime Numbers revolves around Mattia and Alice, friends since high school-'twin primes, alone and lost, close but not close enough to really touch each other,' wherein resides the seductive enchantment of this singular love story."
"This compelling debut shows a remarkable sensitivity and maturity in the depiction of its damaged soulmates. A fragile, unconventional love story by a talent to watch."
"A deeply touching debut. Beautiful and affecting...it reads easily, due in party to the almost seamless translation. An intimate psychological portrait of two 'prime numbers'-together alone and alone together."
"Surprising, intimate and deeply moving, The Solitude of Prime Numbers takes the readers on a hypnotic journey through an unexpected love affair. Paolo Giordano writes with grace and elegance of gentle but damaged characters, using inventive language to create a story unlike anything in recent fiction. This is everything a debut novel should be and leaves one longing for the books that will follow."
-John Boyne, author of The Boy in the Striped Pajamas
"Paul Giordano is an expert on loss and sorrow. He understands and reveals the hidden hollows of the heart. His story is a quiet one, but his strong writing and unforgettable characters make his book a page turner. The Solitude of Prime Numbers is sad, dark and perfect."
-Mary Pipher, author of Seeking Peace: Chronicles of the Worst Buddhist in the World
"What a shock to open a novel written by a young physicist in Italy and find myself there, on every page. No wonder Giordano's readers can be counted in the millions; this astute, aching contemplation of solitude has a power to make us all feel a little less alone. A love story told with astonishing perceptiveness and remarkable subtlety, The Solitude of Prime Numbers is an extraordinary affirmation of the reasons we read."
-Stefan Merrill Block, author of The Story of Forgetting
