This book represents a revision and expansion of an earlier set of diagrams for tempera 0 0 tures from 25 to 300 C along the equilibrium vapor-liquid curve for H 0 (Helgeson, Brown, 2 and Leeper, 1969). The activity diagrams summarized in the following pages were generated over a six year period from 1977 to 1983 in the Laboratory of Theoretical Geochemistry (oth erwise known as Prediction Centra ) at the University of California, Berkeley. They represent the culmination of research efforts to generate a comprehensive and internally consistent set of thermodynamic data and equations for minerals, gases, and aqueous solutions at high pres sures and temperatures. Among the many who contributed to the successful completion of this book, we are especially indebted to David Kirkham, John Walther, and George Flowers, who wrote program SUPCRT, Tom Brown, who created program DIAGRAM, and Eli Mess inger, who generated the Tektronix plot routine to construct the diagrams. Ken Jackson and Terri Bowers both devoted an enormous amount of time and effort over the past six years to produce the diagrams in the following pages; some of which went through many stages of revision. Consequently, they appear as senior authors of this volume. It should be mentioned in this regard that their equal dedication to the project made it necessary to determine their order of authorship by flipping a coin."

London, 1819 Marked for death, Lady Augustine Christopherson finds herself scouring the slums of London in a desperate search to find the men who killed her father, and are determined to dispose of her. To protect her family, to protect herself, she is determined to find the men before they find her. The last thing she wanted was an entanglement with a duke that threatens her very survival... Hardened long ago, the last thing the Duke of Dunway wanted was an entanglement with a chit of the ton. But in the flash of a pistol, his fate is altered as he finds himself honor-bound to protect Lady Augustine from, of all things, herself. The Hold Your Breath series begins. A thousand reasons to hold your breath, and one to let it go. Historical romance with strong women, undeniable men, and hold your breath adventure.
