I added this class:

    public sealed class LinkedBookHeader : Packet
    {
        public LinkedBookHeader(Mobile from, BaseBook book)
            : base(0xD4)
        {
            string title = book.Title == null ? "" : book.Title;
            string author = book.Author == null ? "" : book.Author;
            byte[] titleBuffer = Utility.UTF8.GetBytes(title);
            byte[] authorBuffer = Utility.UTF8.GetBytes(author);
            EnsureCapacity(15 + titleBuffer.Length + authorBuffer.Length);
            m_Stream.Write((int)book.Serial);
            m_Stream.Write((bool)true);
            m_Stream.Write((bool)book.Writable);
            m_Stream.Write((ushort)book.PagesCount);
            m_Stream.Write((ushort)(titleBuffer.Length + 1));
            m_Stream.Write(titleBuffer, 0, titleBuffer.Length);
            m_Stream.Write((byte)0); // terminate
            m_Stream.Write((ushort)(authorBuffer.Length + 1));
            m_Stream.Write(authorBuffer, 0, authorBuffer.Length);
            m_Stream.Write((byte)0); // terminate
        }
    }

And changed this part of the OnDoubleClick method:

            from.Send(new LinkedBookHeader(from, book)); //changed this line
            from.Send(new BookPageDetails(book));
            Toggle = !Toggle;
        }
