Worth taking a brief look how a popular novel translates into sales talk.

Harry has been burdened with a dark, dangerous and seemingly impossible task: that of locating and destroying Voldemort's remaining Horcruxes.
Here we have the protagonist's goal spread before us. We can see that the thing Harry needs is not the thing he wants - he is 'burdened'.
Harry's goal is in direct opposition to the antagonist's: Harry must 'destroy' what Voldemort possesses. We understand that Voldemort would not want his possessions destroyed, although this is not explicitly stated: we recognize through convention that this novel would probably not work so well if Voldemort were willing to have his possessions destroyed by his arch enemy. We need and desire conflict; in this instance, a conflict of interests.
Note the power words: burdened, dark, dangerous, seemingly impossible, destroying.

Never has Harry felt so alone, or faced a future so full of shadows.
We are led to believe that this is the best HP yet, for whatever has come before, not once has Harry felt so alone, etc. Note that the future refers to expectation/anticipation: the reader will want to ride this journey to the future, turning pages along the way.

But Harry must somehow find within himself the strength to complete the task he has been given.
Ah, the inner struggle. Harry didn't ask for this responsibility. If he is to 'somehow' accomplish his goal, he is going to have to dig deep ... to make choices under pressure.

He must leave the warmth, safety and companionship of The Burrow and follow without fear or hesitation the inexorable path laid out for him.
Here is the familiarity of which I have written. This warm and safe haven - this companionship - will allow JKR to cast Harry into peril, even providing a context by which the peril may be perceptually augmented, always having somewhere welcoming to return him too.
More dramatic power words; notably, the word 'inexorable' suggests that the ending may remain open ..?

What on earth are the Deathly Hallows? Who will make it through to the end?
Questions. If you want the answers, you'll need to buy the book! (Well, you could go onto wikipedia instead.)
And, for twelve points, what do questions create? Suspense! Hang tight, beloved HP fans, for the answers are almost upon you.

Okay, we've done the suspense thing - the anticipation. Now, rest assured that the pay-off will be equally fulfilling.
Noteworthy power words are: final, spectacular, spellbinding, richly woven, plunges, twists, breathtaking.
The sales techniques are in force too. In particular, greed is in play, promising the reader value for money: 'will be read, reread, and read again.' Excitement has featured strongly throughout.

And, in case you had missed the subliminal excitement, the excitement is explicitly stated. Always worth repeating these things, hammering upon the customer's defenses.

Now! Do it now! Fear of Loss: what if I don't order it now? What if I order tomorrow morning? Will every copy of this novel be sold out? Jeez, I can't take that risk!
Greed: Save 10%.
Sheep: Well a bit of a no-brainer. However, if you weren't aware that lots and lots of other people are going to purchase this book, be aware that other online bookstores will be stocking it.
Only Indifference is missing from the five key sales techniques. That said, I sense a certain confidence in this sales pitch - a feeling that there are going to be enough consumers to go round.
