Mars Xi can kill you with her mind, but she'll need more than psychic powers to save her in Killing Gravity, the thrilling science fiction space adventure debut by Corey J. White. Before she escaped in a bloody coup, MEPHISTO transformed Mariam Xi into a deadly voidwitch. Their training left her with terrifying capabilities, a fierce sense of independence, a deficit of trust, and an experimental pet named Seven. She’s spent her life on the run, but the boogeymen from her past are catching up with her. An encounter with a bounty hunter has left her hanging helpless in a dying spaceship, dependent on the mercy of strangers. Penned in on all sides, Mariam chases rumors to find the one who sold her out. To discover the truth and defeat her pursuers, she’ll have to stare into the abyss and find the secrets of her past, her future, and her terrifying potential.

Supergravity, together with string theory, is one of the most significant developments in theoretical physics. Written by two of the most respected workers in the field, this is the first-ever authoritative and systematic account of supergravity. The book starts by reviewing aspects of relativistic field theory in Minkowski spacetime. After introducing the relevant ingredients of differential geometry and gravity, some basic supergravity theories (D=4 and D=11) and the main gauge theory tools are explained. In the second half of the book, complex geometry and N=1 and N=2 supergravity theories are covered. Classical solutions and a chapter on AdS/CFT complete the book. Numerous exercises and examples make it ideal for Ph.D. students, and with applications to model building, cosmology and solutions of supergravity theories, it is also invaluable to researchers. A website hosted by the authors, featuring solutions to some exercises and additional reading material, can be found at www.cambridge.org/supergravity.

The 16th conference of the International Society on General Relativity and Gravitation (GR16), held at the International Convention Centre in Durban, South Africa, from 15 to 21 July, was attended by 450 delegates from around the world. The scientific programme comprised 18 plenary lectures, one public lecture and 19 workshops which, excepting three plenary lectures, are presented in this proceedings. It was the first major international conference on general relativity and gravitation held on the African continent.

Corey J. White's space opera Voidwitch Series continues: Mars Xi returns in Void Black Shadow, sequel to Killing Gravity. Mars Xi is a living weapon, a genetically-manipulated psychic supersoldier with a body count in the thousands, and all she wanted was to be left alone. People who get involved with her get hurt, whether by MEPHISTO, by her psychic backlash, or by her acid tongue. It's not smart to get involved with Mars, but that doesn't stop some people from trying. The last time MEPHISTO came for Mars they took one of her friends with them. That was a mistake. A force hasn't been invented that can stop a voidwitch on a rampage, and Mars won't rest until she's settled her debts.
