Tar Pit — Tor Seidler

Edward Small might not be very good at schoolwork or at baseball or be very popular, but he has a truly amazing best friend: an enormous Allosaurus named Alexander who obeys Edward's every command and can crunch Edward's enemies in a heartbeat. There is no place Edward is happier than on the bank of the tar pit where his fantastical friend lives -- but little does he know that something remarkably real is about to emerge from the tarry depths and change his life forever.
