In written French the more usual option is the inversion (as we do in English as well).

Ils lisent des livres.
=> Lisent -
ils des livres? |
|
They read books. => Do they read books? (Read they books?) |

Pronouns that are attached to the verb in these sentences, are connected to them with a hyphen.
There is
one important rule to be taken into account: Only pronouns can be attached this way to a verb, nouns need another construction.
