The Hork-Bajir Chronicles (1966, 1968–69, 1998)
- Although the events in this story occur between The Ellimist Chronicles and The Andalite Chronicles, the entire story is being told by Jara Hamee to Tobias after book #13, The Change, and before the events of #23 The Pretender. Tobias makes reference to his restlessness and the fact that there were no missions planned (Prologue, pg ix). However, in The Pretender, (pg 12) Tobias makes reference to the fact that they had "worked plenty lately, dealing with the horrifying matter of David, the first new Animorph." This places the last possible "break" before book #20, the first book in the David trilogy
