[Tex/LaTex] Biblatex does not print inbook book title

biblatex

I recently started using biblatex and have an extensive bibliograpy file created with bibtex in mind. I compiled my bibliography and notice that InBook looses the book title. As can be seen in the image below only In: gets printed where the book title should be.
Example of formatting

Here is the MWE I used to create this.

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{csquotes}
\usepackage{pifont}
\usepackage[backend=biber,bibstyle=authoryear,citestyle=authoryear-comp,sorting=nyt,mincitenames=1,maxcitenames=2,url=false]{biblatex}
\addbibresource{test.bib}
\author{Minime}
\begin{document}
\parencite{Verwijst2013}
\printbibliography
\end{document}

And this is the format of the entry in the bib file:

@InBook{Verwijst2013,
  Title           = {Development of Sustainable Willow Short Rotation Forestry in Northern Europe},
  Author          = {Theo Verwijst and Anneli Lundkvist and Stina Edelfeldt and Johannes Albertsson},
  Chapter         = {19},
  Editor          = {Dr. Miodrag Darko Matovic},
  Pages           = {479--502},
  Publisher       = {INTECH open},
  Year            = {2013},
  Note            = {Published: April 30, 2013 under CC BY 3.0 license.},
  book            = {Biomass Now - Sustainable Growth and Use},
  Doi             = {10.5772/55072 },
  File            = {Verwijst2013.pdf:Blandat material/Verwijst2013.pdf:PDF}
}

Is there some special treatment by biblatex of InBook, or formatting that I am missing?

The name of the field is booktitle not book. Check the biblatex documentation about the available field names. It contains a long and useful list.
