The Head Shoulders Knees and Toes (HSKT) challenge will be held again in 2018.
The rules will basically stay the same as in previous years (as set by AnOtterChaos, the original host). This explanation has been taken from previous challenge threads with minor alterations:
Open to all, you can enter at any time.
Releases must be made from 1 February to 28 February 2018 (midnight local time).
Book titles and author names count.
There are no minimum requirements for releasing. Both wild and controlled releases will be accepted, although wild releases are preferred. There will be a small prize to the person with the most releases as well as one person drawn at random from all participants who release at least one qualifying book. At the moment, I'm not sure what the prize will be but will probably be wings/membership plus. I'll be participating but will not be eligible for a prize!
The title of the book or author name must contain one or more human body part. Either medical or lay terminology is fine (i.e., shoulder-blade or scapula). Slang is OK as long as it is not offensive.
Embedded words are fine (SHINy, EARth, CHESTnut, chestNUT). (TIP: Any word with 'os' in it counts... os being used to refer to many openings in the body). The embed cannot extend from one word to another (in other words, the embed must be within a single word). If you do use embedded words, please capitalize the embed to make it easier to read (as in the examples above). Subtitles count as well as main titles.
Dual releases are fine. The Valentines Day Challenge offers some good opportunities to show your HEART!
Foreign language words are fine as long as the body part is in the same language as the title.
The challenge is on a MACROSCOPIC level, not MICROSCOPIC. In other words, "bone" is fine, "Osteocyte" isn't. No DNA, chromosome, cell, golgi body, ribosome, etc.
Things that develop throughout life are fine. This includes wrinkles, corns, scars, blisters, freckles, stretch marks, etc.
Body fluids that stay IN the body are fine (blood, lymph, bile).
Body fluids/solids that LEAVE the body are not allowed (saliva, semen, urine, feces, vomit, etc).
Please ask if you're unsure if a word will be allowed.
27. Whistled Like a Bird: The Untold Story of Dorothy Putnam, George Putnam, and Amelia EARhart ( https://www.bookcrossing.com/---/14762532/ ), multiple challenges. (I found a really charming Snoopy-as-pilot LFL located at a small airfield for this one.)
35. 50 Ways to Eat COCK: Healthy Chicken Recipes with BALLs! ( https://www.bookcrossing.com/---/14774084/ ), wild release, multiple challenges, photo. (This one looks like a naughty-bits release, but it really is a cookbook!)
"The true felicity of a lover of books is the luxurious turning of page by page, the surrender, not meanly abject, but deliberate and cautious, with your wits about you, as you deliver yourself into the keeping of the book. This I call reading."
