Doctor Who: New Adventures with the Tenth Doctor #4
One trip, one time, anywhere in the universe. Where and when would you go? In exchange for the invaluable assistance she offered defending New York - and to apologize for dropping into her life like a tornado! - the Doctor has promised Gabby one trip - just one trip! - in the TARDIS. With the whole universe laid before her, all of time and space, where will Gabriella Gonzalez choose to go? What will they find when they get there - and can one trip in the TARDIS ever be enough? More importantly, with Donna still fresh in the Doctor's mind, can Gabby convince him that he shouldn't travel alone, for just a little while longer?
