Secrets of the past hold the key to the future. Joseph Bridgeman is now an official member of the Continuum, a group of time travelers that heal the past to protect the future. When a rare focus object is stolen and put up for sale, Joe jumps at the chance to retrieve it, but a simple auction turns into a dangerous new mission that takes him farther back in time than he’s ever been before. Alone and unprepared in ancient China, Joe must not only complete the mission, but also unravel the mystery of a secretive organization known as Extempero. Who are they? And why do they seem intent on destroying everything the Continuum has achieved so far? When all hope appears lost, an unexpected ally helps Joe unlock a unique form of time-travel loop that sees him flung into the past yet again. Caught up in a shocking natural disaster, Joe must face a terrible choice, a decision that will have far-reaching consequences for the Continuum and a delicate future that hangs in the balance.

He only looked away for a second. Still haunted by the disappearance of his little sister, Amy, over twenty years ago, Joseph Bridgeman’s life has fallen apart. When a friend talks him into seeing hypnotherapist Alexia Finch to help with his insomnia, Joseph accidentally discovers he can time travel. His first trip only takes him back a few minutes, but his new-found ability gives him something he hasn’t felt for the longest time: hope. Joseph sets out to travel back to the night Amy went missing and save her. But after several failed attempts, he discovers the farther back he travels, the less time he gets to stay there. And the clock is ticking. With the help of Alexia, Joseph embarks on a desperate race against the past to save his sister. Can he master his new skill and solve the mystery of Amy’s disappearance before it’s too late? Previously released as The Unexpected Gift of Joseph Bridgeman, this updated version includes extra chapters, new plotlines, and even deeper character development. It makes way for an expanded vision of the Joseph Bridgeman Series, with the first four books released in 2021 and 2022.

The Quantum Challenge, Second Edition, is an engaging and thorough treatment of the extraordinary phenomena of quantum mechanics and of the enormous challenge they present to our conception of the physical world. Traditionally, the thrill of grappling with such issues is reserved for practicing scientists, while physical science, mathematics, and engineering students are often isolated from these inspiring questions. This book was written to remove this isolation.

Describing the physical properties of quantum materials near critical points with long-range many-body quantum entanglement, this book introduces readers to the basic theory of quantum phases, their phase transitions and their observable properties. This second edition begins with a new section suitable for an introductory course on quantum phase transitions, assuming no prior knowledge of quantum field theory. It also contains several new chapters to cover important recent advances, such as the Fermi gas near unitarity, Dirac fermions, Fermi liquids and their phase transitions, quantum magnetism, and solvable models obtained from string theory. After introducing the basic theory, it moves on to a detailed description of the canonical quantum-critical phase diagram at non-zero temperatures. Finally, a variety of more complex models are explored. This book is ideal for graduate students and researchers in condensed matter physics and particle and string theory.
