Bookstore Day marks its second year of celebrating independent bookstores nationwide on April 30 with literary parties around the country.

Square Books will celebrate all day at all 3 stores with refreshments, raffle drawings, giveaways, a book sale and an “Ask an Author” booth from 10:30 a.m. to 4 p.m., which will allow customers to ask a local author a question about any topic — books, relationships, sports, current affairs, etc.

Square Books also will offer exclusive day-of merchandise created especially for Independent Bookstore Day by major publishers and authors. Since its inception in 2014, more than 120 authors have demonstrated their support for independent bookstores by donating work for Bookstore Day.

The second annual National Independent Bookstore Day is sponsored in part by Penguin Random House, Ingram, and The American Booksellers Association. Last year participating bookstores saw an average increase in sales of 70 percent on Independent Bookstore Day.
