NEW YORK (AP) — A new and uncertain era of e-book prices has begun.

HarperCollins announced Tuesday that it has reached new price agreements with retailers. The move conforms to a settlement with the Justice Department over allegations that five publishers and Apple had colluded to set prices for e-books. Such new works as Michael Chabon's "Telegraph Avenue" now can be purchased on for $9.99, a price publishers and rival booksellers fear will give Amazon dominant control of the e-market.

Simon & Schuster and Hachette Book Group also settled, but as of late Tuesday morning e-prices for such fall books from those publishers as Bob Woodward's "The Price of Politics" and Tom Wolfe's "Back to Blood" were selling for $14.99. Two other publishers, Penguin Group (USA) and Macmillan, declined to settle and a trial is expected next June.
