The Dog at the Foot of the Bed

Sixteen years ago the Shannen children were attacked and their home was destroyed. The oldest--twins Ovin and Siobhan--barely managed to whisk their siblings away to safety on a remote planet. Seeking revenge for the attack, Ovin became a hired assassin, while Siobhan entered corporate security service to bring about law and order--and to bring Ovin to justice.

Now someone is trying to kill the Shannens again. And another threat has surfaced: a terrible new weapon is cracking planets open like nuts and destroying them--a weapon that could be used on the Shannens' new home. Ovin has to find out who is behind these murderous projects, and stop them--but in order to find out who, he first has to discover why . . . and he's going to need Siobhan's help to do it.

But if he succeeds, he could lose his twin forever.
