The White House is keeping Obama's talent a closely guarded secret. Several friends and family members will join the Obamas at their rented oceanfront home in Kailua.
Obama has stayed under the radar for much of his Hawaiian vacation, mostly spending his time at the gym, golf course or beach.
The White House says he has been reading three books: Lou Cannon's biography of Ronald Reagan, "President Reagan: The Role of a Lifetime"; and two novels, "The Thousand Autumns of Jacob de Zoet", by David Mitchell, and "Our Kind of Traitor", by John le Carre.
