Just like fashions, books come in and out of popularity. The new “in” books at Mark Morris often involve vampires and other non-human creatures, like fallen angles and urban faeries.

Of course, there’s the increasingly popular “Twilight” series, but other popular titles include “City of Bones,” “Vampire Academy,” “Fallen” and “Tithe.”

“So many people like Stephanie Meyers’ “Twilight” that they’re looking for more books like it,” says Mark Morris librarian Patti Tjomsland. Furthermore, Tjomsland predicts that these popular genres are going to stay around for a while.

Fallen angels are stories about angels whose wings are clipped, they then fall to earth, creating havoc wherever they go like in “Fallen” and “Hush Hush.” Urban faeries are stories about faeries living in modern times. Two popular titles are “Tithe” and “Wicked Lovely.” Some popular vampire stories are “Blue Bloods,” “Vampire Academy” and “Vampire Diaries.”

Another series growing in popularity is Cassandra Clare’s “Mortal Instruments.” This is a three-book series, with still another book in the works. “City of Bones,” “City of Ashes,” and “City of Glass” are books about vampires, werewolves, warlocks, faeries, demons, and the people with the power to destroy them. These books are so popular that Tjomsland rarely gets to put them on the shelves, because they are checked out so quickly.

Stories about human and nonhuman couples are what readers are really interested in reading. These are really basic romance stories with a twist. There’s also more interest in reading stories about events that take place now, rather than in the past.

Past or present, these are the books that are going to be popular.
