Respond to node deletion.
This hook is invoked from node_delete_multiple() after the type-specific hook_delete() has been invoked, but before hook_entity_delete and field_attach_delete() are called, and before the node is removed from the node table in the database.
Parameters
$node: The node that is being deleted.

Possbile to stop deletion with this hook?
Is it possible to stop deletion of this hook? Say, by returning false?
I'm aware of the consequences of creating a "protected" node.
Unfortunately No
No, take a look at node_delete_multiple(). To cancel using this hook, you would essentially be stopping in the middle of deleting data. Even giving your module a light weight wouldn't get it to the front of the line, as the module defining the content type has its hook_delete() called first.
No hooks that provide an opportunity to cancel the operation are called before the deletion process starts. You could throw an exception that causes a db transaction rollback, but I strongly encourage against that.
