Invaders from the Infinite is a science fiction novel by American writer John W. Campbell Jr.

Eshbach eventually did produce a jacket in 1990 at the urging of George Zebrowski.

E. F. Bleiler described the novel as "the early John W. Campbell story par excellence: weak novelistic skills combined with very strong speculative, imaginative theoretical physics.

While one may be bored with [the] interminable lectures and rendered drowsy by the repeated space battles, but one must also admire Campbell's ingenuity in creating novel artifacts".

[1] The novel, a sequel to The Black Star Passes and Islands of Space, concerns a trio of heroes, Arcot, Morey and Wade, and their attempts to help a race of superdogs.
