Cast on 10 sts
Row 1: [k1, yo twice, k1], k7 wt
row 2: slip 1, k7, [k2, p1, k1].
row 3: [k4], k6, wt.
row 4: slip 1, k6, [k2tog twice, loosely].
OK, let's see.
On row 1, you're using 9 of the stitches, but not knitting the last one. Instead, you will wrap the last stitch to avoid a hole and just slip it. When you w&t, you bring the yarn to the front, slip the next stitch, bring the yarn to the back and slip the stitch back. In this case, I believe, you'll end up with the wrapped stitch still on your left needle when you turn. The yarn will be in the front, but I think you'd just put it to the back and slip the first stitch of row 2, purlwise.
You started with 10, and you do a double wrap on row 1, so you'll have 12 stitches to work on row 2, including the wrapped stitch.
On Row 3, you're only using 10 of the 12, leaving the two on the needle.
Check out the video on 'wrap & turn' if you're unsure how to do it; it looks like you're working short rows on the odd rows and all the stitches on the evens.
BTW--it's OK to post the name of the book, so if any of us have it, we can look at the pattern.
