The Dog at the Foot of the Bed by Tyree Campbell
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.
“Campbell’s novel is a guessing game that will keep you wrong-footed until the very last page.” – Edward Cox, [UK] Reviewer
