The Penguin Group is a trade book publisher, the second largest in the world, after Random House. The Penguin Group is the name of the incorporated division of parent Pearson PLC that oversees these publishing operations. Penguin Books has its registered office in City of Westminster, London, England.

Its British division is Penguin Books Ltd. Other separate divisions can be found in the United States, Ireland, New Zealand, India, Australia, Canada, China and South Africa.

Penguin Books Ltd. (est. 1935) of the United Kingdom was bought over by Pearson Longman in 1970.

Penguin Group (USA) Inc. was formed in 1996 as a result of the merger between Penguin Books USA and the Putnam Berkley Group. The newly formed company was originally called Penguin Putnam Inc., but in 2003 changed its name to Penguin Group (USA) Inc. to reflect the parent Pearson PLC's grouping of all the Penguin companies worldwide under the supervisory umbrella of Pearson's own Penguin Group division.

The different Penguin companies use many imprints, many of which used to be independent publishers. Penguin Group (USA) Inc. also operates its own speaker's bureau that books speaking engagements for many of the publisher's authors.

Richelle Mead (born November 12, 1976) is a bestselling American fantasy author. She is known for the Georgina Kincaid series, Vampire Academy, and the Dark Swan series.

Richelle Mead was born in Michigan and currently lives in the Seattle suburb of Kirkland, Washington, United States. She has three degrees: a Bachelor of General Studies from the University of Michigan, a Master of Comparative Religion from Western Michigan University, and a Master of Teaching from the University of Washington. Her teaching degree led her to become an 8th grade teacher in suburban Seattle, where she taught social studies and English. She continued writing in her free time, until she sold her first novel, Succubus Blues. After quitting her job to write full time, her other books quickly followed.

It is an upcoming Adult Series.

Mead is writing a six-book spin-off series featuring characters in the Vampire Academy series: Sydney, Jill, Eddie, and Adrian. "Spin off series takes place in the same universe as Vampire Academy. Same rules, same races. What happens here is that the side characters from Vampire Academy are now the main characters. And so the series will be following Sydney, Jill, Adrian, and Eddie". Mead has confirmed that Bloodlines will be the name of both the series and the first book.
