A lot of things and stories have been written about the SEALs, but there is still a lot that we can learn from this elite group of soldiers. Photographers Stephanie Freid-Perenchio and Jennifer Walton gives readers a rare glimpse into the lives of those who are given the privilege to call themselves Navy SEALs with the release of their collaborative coffee table book, “SEAL: The Unspoken Sacrifice”. The book is the fruit of eight years’ worth of work from the two photographers.
