I am a librarian, and it seems books are going to be my only companions.

One lunatic who'd just lost or killed his only companion.

Imagine having a dragon as your only companion for over a century.

The voice had been a comfort sometimes, his only companion.

Being his only companion, he is very protective of it.

More than anything, he wanted to save this woman who had been his only companion for two days.

No, the only companions he could imagine for what lay ahead were men.

She is a lonely girl, and books are her only real companions.

She and the son turn up on the same day he loses his only companion?

"Or is he not the only companion you have found?"
