Eric Marcus’ classic 2001 instructional book, What If Someone I Know Is Gay? (Simon & Schuster/Simon Pulse, $8.99), has been reissued.

In the revised edition, Marcus offers teens answers to a variety of questions covering many topics, including how gay people have sex, why gay people attend pride parades and the meaning of ‘queer’. There is also now a chapter specifically for parents as well as other updates, revisions and additions.

Among Marcus’ other books are Making Gay History, Why Suicide? and the best-selling Greg Louganis autobiography Breaking the Surface.
