Two special guests are slated to visit Eagle Harbor Book Company in downtown Winslow on Thursday, July 28 for a young adult doubleheader literary lollapalooza.

First, at 10:30 a.m., Annabella Serra of The Lost Quill will come by to lead a handwriting workshop.

She’ll use the book “The Day the Crayons Quit” and guide young writers in the craft of tactile writing.

This event will be part of the Eagle Harbor Summer Books Passport Program for young readers. Sign up and sign in at each event, and you’ll earn books at the end of the summer if you attend five or more events.

There will be two sessions with Serra, the second at 4 p.m.

Sign up at www.eagleharborbooks.com to attend.

Then, at 7:30 p.m., award-winning science fiction/fantasy author David D. Levine will be at the shop to discuss his first novel, “Arabella of Mars.”

In this alternate history adventure, the headstrong teenager Arabella disguises herself as a boy to sneak on a ship bound for Mars on a mission to save her brother and their family.

Since Newton witnessed a bubble rising from his bathtub, mankind has sought the stars. When William III of England commissioned Captain William Kidd to command the first expedition to Mars in the late 1600s, he proved that space travel was both possible and profitable. Now, one century later, a plantation in a flourishing British colony on Mars is home to Arabella Ashby, a young woman who is perfectly content growing up in the untamed frontier. But days spent working on complex automata with her father, or stalking her brother Michael with her Martian nanny, is not the proper behavior of an English lady. That is something her mother plans to remedy with a move to an exotic world Arabella has never seen: London, England.

However, when events transpire that threaten her home on Mars, Arabella decides that sometimes doing the right thing is far more important than behaving as expected. She disguises herself as a boy and joins the crew of the Diana, a ship serving the Mars Trading Company.

Now Arabella just has to weather the naval war currently raging between Britain and France, learn how to sail, and deal with a mutinous crew if she hopes to save her family on Mars.

Levine is the author of more than 50 science fiction and fantasy stories. His story “Tk’Tk’Tk” won the Hugo Award in 2006, and he has been shortlisted for such awards as the Nebula, Campbell, and Sturgeon. His stories have appeared in Asimov’s Science Fiction, Analog, The Magazine of Fantasy & Science Fiction, five Year’s Best anthologies and his own award-winning collection “Space Magic.”

He lives in Portland, Oregon.
