UCSB Arts & Lectures announced Monday that Khaled Hosseini has canceled all speaking engagements, including his Santa Barbara date at the Arlington Theatre on Tuesday, because of his father’s emergency hospitalization.

There are no plans to reschedule the event at this time.

Arts & Lectures has requested that the UCSB Accounting Office refund patrons the full price of tickets purchased. Refunds should arrive in the mail in the next several weeks.
