The 15th Literary Orange festival of books will go virtual in April with keynote speakers that include 2020 National Book Award winner Charles Yu and best-selling thriller writer Harlan Coben.

A year ago, Literary Orange was swept up in the first wave of cancellations in the COVID-19 pandemic. Instead of the annual day of celebrating authors and their books, the event went dark in 2020.

This year, the festival hosted by OC Public Libraries since 2007 will present five authors on the bill. The virtual events will take place over four Wednesdays in April with a bonus VIP program on May 13.

The schedule kicks off with Coben, whose new book “Win” arrives in mid-March, on April 7. Australian historical novelist Heather Morris (“The Tattooist of Auschwitz,” “Cilka’s Journey”) is April 14.

On April 21, novelist Lisa Wingate (“Before We Were Yours,” “The Book of Lost Friends”) will appear. And on April 28, Charles Yu, whose novel “Interior Chinatown” won the National Book Award in November, will wrap up the regular series.

A special VIP bonus program for those who buy tickets to the previous four programs will present writer Lisa See in virtual conversation on May 13.

Tickets are $25 each for the regular programs, which includes a copy of the author’s most recent book. A pass for the four regular programs is $75. The four programs plus the VIP with See is $85.
