What paranormal romance books should I read?

As many of you know, I'm away soon on a jaunt around Europe by train (my husband's way of getting to the Barca vs Real Madrid classico when I didn't want to fly so soon after my ear operation - and they say women are devious). So, I'll have three weeks of travel to fill with books and some long train journeys (over 7 hours for two of them) that will need entertainment to stave off boredom. There's only so much time a girl can spend staring out of the window / talking to her better half. He'll be practicing his Spanish and other languages anyway.

I want to take my Kindle with me because it's a nightmare to carry enough clothes for three weeks in a backpack let alone carrying paperbacks too.

I am getting some amazon.co.uk vouchers for my birthday so I'll be looking to spend those...

Here's the books I was considering buying:

Larissa Ione's Demonica Series - Desire Unchained, Passion Unleashed
(I've read the first book, and own Ecstasy Unveiled in pb)

Gena Showalter's LOTU Series: The Darkest Surrender, The Darkest Seduction 
(I have them in pb but will buy Kindle so I can read them on my travels)

Lara Adrian's Midnight Breed Series: Darker After Midnight
(I own this in pb but will buy Kindle as I have the rest of the series in both formats)

Kresley Cole's Immortals After Dark Series
(I've read A Hunger Like No Other years back and gave it a 2 star. Just didn't like it but willing to give the series a second chance if people say it gets better)

Anything else I should consider buying?

Here's the books on my Kindle right now:

Lara Adrian's Midnight Breed Series: Deeper Than Midnight

Gena Showalter's Atlantis Series: The Nymph King, The Vampire's Bride

J R Ward's Black Dagger Brotherhood Series: Lover Eternal
(I have Lover Avenged too but that's book 7, and have Crave in her fallen angels series, but that's book 2... not read book 1)

Lynsay Sands Argeneau Vampires Series: Vampires Are Forever, Vampire Interrupted, The Rogue Hunter... and up to book 13 in the series

Dani Harper's Changeling Moon

Karen Marie Moning's Darkfever

Jacquelyn Frank's Nightwalker Series: Jacob

Oh, what shall I read?
