Like the previous onebook, this bookone ends on a tragic note. For Harry, Sirius' death creates yet another deep void in his life, althoughthough, unlike when his parents died, it is the first time he has lost a loved one that he actually knew and had a lengthy relationship with. Not only is he filled with grief, but also guilt over his rash behavior and the mistakes he made, which led to the tragedy and nearly cost his friends their lives. Although Harry blames himself for Sirius' death, he fails to recognize that his godfather's reckless behavior also significantly contributed to his own demise. He also blames Dumbledore for withholding information, and Snape, who, despite Dumbledore's unwavering faith, he believes deliberately waited too long to warn [[Muggles' Guide to Harry Potter/Major Events/Order of the Phoenix|the Order of the Phoenix]]. Harry's attempts to contact Sirius in the afterlife indicates he ishis unwillingunwillingness to accept that his godfather is truly gone, althoughthough hisLuna's talk with Lunawords provides some comfort and bolsters his hope that there may actually be an afterlife.
Harry realizes that Voldemort is an even greater threat, and althoughthough he now knows that returning to [[Muggles' Guide to Harry Potter/Places/Privet Drive|Privet Drive]] each summeryear sustains his mother's magical charm that protects him, this understanding provides little comfort as he prepares to endure yet another cheerless summer with the Dursleys. Harry will have time to reflect on what has happened and hopefully learn from his mistakes, althoughthough his path to maturity has been more traumatic than most. Mourning Sirius' death will cause him to feel even more alone and unloved, and likely will cause him to isolate himself, as he often does during stressful times. As a result, he can overlook or shut out those people left in his life who care for and support him. As he grieves his lost godfather, Ron, Hermione, Lupin, Dumbledore, and the others draw closer to him; they are his true "family."
