This pattern is available here and as part of Ar Book here.

Sleepless Heart it’s a crescent shaped shawl knitted top-down. The center section has a romantic lace pattern resembling hearts and a wavy lace ribbing on the sides. All the three sections dissolve into a striking edging.
As shown, the shawl is finished with a picot bind-off for extra loveliness, but instructions for an elastic bind-off are also included.

Other info:

Materials: Approx 830.8m m of sport yarn; st markers; size 4.5 mm (US 7) circular needles; size 6 mm (US 10) for the bind-off, tapestry needle; pins for blocking; I recommend using a fiber with at least 70% wool or other animal fiber content and wet block the shawl.
You may use DK or fingering yarn, yardage will vary depending of yarn weight, needle size, gauge and number of pattern repeats.

Level: Advanced - This project is suitable for fearless knitters with experience knitting lace on both sides of work (wrong side and right side rows) and manipulating unusual stitches (lace, ribbing, textures, cast-on and drop sts throughout the pattern and all sort of increases and decreases). That said, the abbreviations are detailed, I included a tutorial explaining unusual stitches, added charts with check boxes with the stitch count per row and the format is very clean and friendly.

Skills needed: provisional cast-on, K, P, P2tog, Ssp, YO, Dyo, K2tog, Ssk, M1R, M1L, elastic BO or picot BO, single cast-on, Kf&b, drop sts, knit sts from previous rows (fully explained into pattern). Wet block the shawl and woven in ends.

Pattern format: Both written instructions (line by line) and charts are provided. Pattern is a pdf file document and you need Adobe Acrobat Reader application to open it.

Many thanks to my wonderful testers:
